Abstract

Silver nanoparticles destruction process in photo-thermo-refractive glass under nanosecond pulsed laser irradiation (532nm) depending on exposure dose is investigated. It is shown that photo fragmentation of silver nanoparticles and formation of silver clusters as well as the photoionization of silver neutral atoms with their transition into ion state takes place under laser radiation.

Keywords: photo destruction, photo-thermo-refractive glass, silver nanoparticles
