At the beginning of the heating of the colloid, the sharp edges of the nanoprisms are truncated. At the later stages of the heating, the shape of the colloid is disk. Owing to the shape transformation of the colloid, the plasmon resonance frequency of the colloid blue shifts. When the temperature of the heating is decreased to low temperatures, for example 60 °C, the shape conversion is slowed down. Remembering the boiling temperature of water at around 100 °C, heating temperature just below the boiling temperature of water is enough to convert nanoprisms to nanodisks.
- J-aggregate dyes were used and they were mixed with plasmonic nanoparticles. Note that some dyes show J-aggregate properties at high concentration. Although the J-aggregate dyes have very broad absorption band in the monomer form, they have very sharp absorption band in the aggregated form. This is due to the dipole-dipole coupling of the dye molecules and they have very sharp and red-shifted absorption band.

The field of the invention
This invention is related to the synthesis method of nanodisk shaped colloidal plexcitonic nanoparticles. The hybrid nanoparticles, stable, water soluble, having large Rabi splitting energies, can be transfered to any desired chemically modified surfaces. The plexcitonic nanoparticles reported in this invention may find applications in laser fabrication, biosensors, and energy transfer studies at nanoscale dimension. Nanodisk shaped colloidal plexcitonic nanoparticles show half-plasmonic and half-excitonic properties and thus they are polaritonic nanoparticles and they can be used in polaritonic laser applications.

Background
In the strong coupling regime, when plasmonic nanoparticles are combined with excitonic sources having the same resonance frequency plasmon-exciton hybrid nanoparticles are formed. In this strong coupling condition, the splitting in the resonance frequency has been observed. The magnitude of the splitting in the energy levels strongly depends on the amount of excitonic materials placed on the plasmonic nanoparticles. The new hybrid nanoparticles show both plasmonic and excitonic properties. The hybrid nanoparticles containing both metallic and organic parts are called plexcitonic nanoparticles.
Until now, various shaped plasmonic nanoparticles have been used for the synthesis of plexcitonic nanoparticles. Most commonly, nanoprism shaped plasmonic nanoparticles have been used for the synthesis of plexcitonic nanoparticles. However, colloidal nanoprism shaped plexcitonic nanoparticles can not be stored in aqueous medium for a long time, which limits their use in a variety of fields such as sensors, lasers, and solar cells.
Summary and aims of the invention
The current invention is about synthesis method of nanodisk shaped plexcitonic nanoparticles having the superior properties mentioned above.
In this invention, nanodisk shaped plasmonik nanoparticles are uniformly coated with dye molecules and the resulting hybrid nanoparticles show half-excitonic and half-plasmonic properties. The new hybrid nanoparticles have very large Rabi splitting energy of 350 meV at room temperature. The giant Rabi splitting energy observed in the hybrid nanoparticles reflects the interaction strength between plasmonic nanoparticles and dye molecules. The splitting energy is more than 15% of the resonance energy of the individual bare plasmonic nanoparticles and dye molecules, which shows that coupling between the plasmonic and excitonic systems is very large and hence the coupling is indeed in the ultrastrong coupling regime. The synthesized hybrid nanoparticles can be stored in an aqueous medium and can be placed on any surface after chemical modification of the target surfaces.

Owing to their both plasmonic and excitonic properties, the nanodisk shaped plexcitonic nanoparticles may find applications in both plasmonic and excitonic investigations. Therefore, the application area of the hybrid nanoparticles can be both plasmonic and excitonic studies in universities and hig technology firms focussed on solar cells, lasers, and biosensors.
The current invention shows for the first time that colloidal nanodisk shaped plasmonic nanoparticles can be converted to colloidal plexcitonic nanoparticles. Firstly, the silver nanoprism nanoparticles are converted to silver nanodisk nanoparticles and then the bare nanodisk nanoparticles are uniformly covered with excitonic dye molecules at room temperature.
The plexcitonic nanoparticles reported in this invention are stable in aqueous medium and therefore, they can be prepared as a commercial product and they can find applications in various fields.

The well-known nanoprism shaped plexcitonic nanoparticles show variation in their optical and chemical properties as a function of time due to their degradation in aqueous solution at room temperature. On the other hand, the nanodisk shaped plexcitonic nanoparticles reported in this invention are very stable for a long time in
aqueous solution and at room temperature. In this invention, nanodisk shaped plexcitonic nanoparticles are reported and there are no difficulties and obstacles for commercial presentation of the nanodisk shaped plexcitonic nanoparticles.

Detailed discussion of the invention
This invention is about synthesis method of single crystal nanodisk shaped plexcitonic nanoparticles, which are very stable in water and have large Rabi splitting energies.
This invention contains the following synthetic steps to reach colloidal nanodisk shaped plexcitonic nanoparticles,
1. Spherical shaped silver nanoparticle synthesis
2. Synthesis of silver nanoprism
3. Synthesis of silver nanodisk
4. Synthesis of plexcitonic nanoparicle steps.
In order to synthesize plexcitonic nanoparticles, firstly, spherical shaped silver nanoparticles are synthesized in aqueous medium. Spherical silver nanoparticles were synthesized by
mixing 5 mL of 2.5 mM trisodium citrate with 0.25 mL of 500 mg/mL poly(sodium 4- styrenesulfonate), and 0.3 mL of 10 mM sodiumborohydride. Subsequently, 5 mL of 0.5 mM silvemitrate was added drop-by-drop with a rate of 2 mL/min. After half an hour, appearance of yellow colored solution is a strong indication of spherical silver nanoparticle formation. In addition to the above described sythesis method of silver nanoparticles, there are variety of synthetic methods for the synthesis of spherical silver nanoparicles.
By using spherical silver nanoparticles as seeds, nanoprism shaped silver nanoparticles can be synthesized. The spherical silver nanoparticles have plasmon resonance wavelength at around 400 nm. In order to tune the plasmon resonance wavelength, the sahpe of the silver nanoparticles has to be changed. The anisotropic silver nanoparticles have plasmon resonance wavelength from 400 nm to 1100 nm. It should be noted here that the number of spherical silver nanoparticles present in the reaction medium determine the size and therefore the resonance wavelength of the plasmonic nanoparticles. For the synthesis of nanoprism shaped silver nanoparticles, 75 pL of 10 mM ascorbic acid was added to 5 mL of water. While the acidic solution was stirred at 200 rpm with a magnetic stirrer, varying amounts of silver nanoparticle seeds were added. It is noteworthy that the number of seed nanoparticles determine the final size of the silver nanoprism and hence the plasmon resonance frequency of the silver nanoprism. For example, in order to have plasmon resonance at around 600 nm, 200 pL silver nanoparticle seeds were added to the reaction solution. 3 mL of 0.5 mM silver nitrate solution was added drop by drop to the reaction solution with a rate of 1 mL/min. Finally, 0.5 mL of 25 mM trisodium citrate as a stabilizer of the colloid was added to the plasmonic nanoparticles. The resonance frequency of the plasmonic nanoparticles can be tuned by varying the number of seed nanoparticles used in the reaction. The stability problem observed in the nanoprism shaped plexcitonic nanoparticles was totally removed in this study by converting nanoprisms to nanodisks plasmonic nanoparticles and then coating with excitonic sources.
In order to convert silver nanoprisms to silver nanodisks, the nanoprism colloid was heated under stirring in an oil bath at 95 °C for about half an hour. During heating of the colloid in the oil bath, the color of the colloid was blue shifted. Depending on the duration of the heating, the shape of the plasmonic nanoparticles shifts from nanoprism to nanodisk. At the beginning of the heating of the colloid, the sharp edges of the nanoprisms are truncated. At the later stages of the heating, the shape of the colloid is disk. Owing to the shape transformation of the colloid, the plasmon resonance frequency of the colloid blue shifts.
When the temperature of the heating is decreased to low temperatures, for example 60 °C, the shape conversion is slowed down. Remembering the boiling temperature of water at around 100 °C, heating temperature just below the boiling temperature of water is enough to convert nanoprisms to nanodisks.
In order to synthesize plexcitonic nanoparticles from plasmonic nanoparticles, J-aggregate dyes were used and they were mixed with plasmonic nanoparticles. Note that some dyes show J-aggregate properties at high concentration. Although the J-aggregate dyes have very broad absorption band in the monomer form, they have very sharp absorption band in the aggregated form. This is due to the dipole-dipole coupling of the dye molecules and they have very sharp and red-shifted absorption band. In this invention, (5,5',6,6'-tetrachlorodi(4- sulfobutyl)-benzimidazolocarbocyanine(TDBC) was used a J-aggregate dye and an excitonic source in plexcitonic nanoparticle formation. As an excitonic source, in addition to semiconducting quantum dots, dye molecules with varying emission wavelengths can be used. Varying amount of 1 mM TDBC dye was added to plasmonic nanoparticle colloid. The color of the colloid suddenly turns from blue to purple color. The Rabi splitting energy representing the strength of the plasmon-exciton coupling in plexcitonic nanoparticles can be controlled by varying the amount of J-aggregate dye added to the plasmonic colloid. The Rabi splitting energy is directly proportional to the square root of the dye concentration.
