Investigating exciton-plasmon interaction in an ion-exchanged glass covered by silver iodide nanoparticles — •Razieh Talebi — Department of Physics, University of Isfahan, 81747-73441 Isfahan, Iran — Department of Physics, University of Isfahan, 81747-73441 Isfahan, Iran

Silver nanoparticles embedded in dielectric or semiconductor films have attractive optical properties that make these materials to be used as plasmonic sensors and waveguides. The silver ions are doped in a thin layer of glass under ion-exchange process. Subsequently, the silver nanoparticles can form in this layer by post-annealing treatment which is tracked by in-situ XRD pattern. The exciton of semiconductors such as silver iodide can interact with the localized surface plasmon resonance of silver nanoparticles. The exciton-plasmon interaction in an ion-exchanged glass covered with silver iodide is investigated by absorption spectra at room temperature. The spectra of these materials before and after silver iodide nanoparticles are exposed, are compared.
