  • 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.
  • the colloidal plexcitonic nanoparticles are very sensitive to the change in the refractive index of the medium and therefore they can be used in sensor applications.

  • 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.
  • the nanodisk shaped plexcitonic nanoparticles can be stored in water for several months and therefore the nanodisk samples in water can be prepared as a commercial product. 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. It should be noted here that silver nanodisks are more stable than silver nanoprisms. At room temperature, the silver nanoprisms degrade from their sharp corners (truncation) and thus they cannot be stored at room temperature for a long time, which limits their applications in various fields.

  • TDBC 5,5',6,6'-tetrachlorodi (4-sulfobutyl)- benzimidazolocarbocyanine
  • 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,
  • 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.
  • nanoprism shaped silver nanoparticles can be synthesized.
  • the spherical silver nanoparticles have plasmon resonance wavelength at around 400 nm.
  • 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.
  • nanoprism shaped silver 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.
  • plasmonic nanoparticles 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.
  • 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.
  • 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.
  • TDBC (5,5',6,6'-tetrachlorodi(4- sulfobutyl)-benzimidazolocarbocyanine
  • TDBC a J-aggregate dye and an excitonic source in plexcitonic nanoparticle formation.
  • 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.

De plus, les nanoparticules plexcitoniques colloïdales sont très sensibles à la variation de l'indice de réfraction du milieu et par conséquent elles peuvent être utilisées dans des applications de capteur. Les nanoparticules plexcitoniques colloïdales en forme de nanodisque sont en milieu aqueux et elles peuvent être utilisées dans des applications à la fois plasmoniques et excitoniques. Les laboratoires de recherche et développement dans les universités et les entreprises de haute technologie peuvent être très intéressés par les nanoparticules plexcitoniques colloïdales.
