Laser annealing of metal nanoparticles synthesized in glasses by ion implantation
Recent results on the interaction of high power laser pulses with dielectrics containing metal nanoparticles are observed. The excimer laser pulse modification of copper nanoparticles synthesized by ion implantation in silicate glass are considered. Pulsed laser irradiation makes it possible to modify such composite layer, improving the uniformity in the size distribution of the nanoparticles. Changes induced by pulsed laser exposure suggest there are both reductions in average size of the metal nanoparticles, and some long-range dissolution of metal atoms in the matrix. Experimental data on laser modification are explained by photofragmentation of the nanoparticles in the dielectric matrix.
