Formation of Plasmon–Exciton Nanostructures upon Decorating Ag2S/SiO2 Quantum Dots with Au Nanoparticles
The formation of plexcitonic nanostructures upon decorating the surface of Ag 2 S/SiO 2 quantum dots with small Au nanoparticles (around 2.0 ± 0.5 nm) is confirmed spectroscopically. It is established via IR spectroscopy that two mechanisms which depend on the charge state of the Au nanoparticle sur...
