摘要
It is shown that pulsed irradiation (a wavelength of 10.6 mu m and an energy density of 0.6-8.5 J cm(-2)) of glass with a waveguide layer containing silver ion leads to the formation of a ring, surrounding the irradiated zone and consisting of silver nanoparticles deposited on the glass surface. The possible process of formation of silver nanoparticles under laser irradiation is discussed.
