Optical Properties of Ag Nanoparticle-Glass Composites
Silver nanoparticles doped glass composites were prepared by ion-exchange and subsequent thermal treatment processes.The optical properties of silver nanoparticle-glass composites were investigated by UV-VIS spectrophotometer and z-scan technique.The results show that the optimal Ag+/Na+ ion-exchange temperature range is between 310℃ and 380℃,higher ion-exchange temperature or higher AgNO3 concentration in melt or longer ion-exchange period favors the introduction of more Ag+ ions into soda lime silicate glasses.The higher Ag+ concentration introduced into silicate glass,the larger the volume fraction ofAg nanoparticles in glass after annealing will be.Ag nanoparticles size and volume fraction become larger with increasing the annealing temperature and extending the annealing time.The off-resonant third-order nonlinear optical susceptibility of Ag nanoparticle-glass composite exhibits a value of 1.16× 10-10 esu where the real part is-1.15× 10-10 esu,and imaginary part is 1.4× 10-11 esu.
