Abstract
Silver nanoparticles doped glass composites were prepared by ion-exchange plus thermal treat- ment.The optical properties of silver nanoparticle glass composites were investigated by UV-VIS spec- trophotometer and Z-Scan technique.The results show that the optimal Ag~+/Na~+ ion-exchange tem- perature is between 3100C and 380℃,higher ion-exchange temperature or higher AgNO_3 concentration in molting bath or longer ion-exchange period favors the introduction of more Ag~+ ions into soda-lime silicate glass.The higher Ag~+ concentration introduced into silicate glass is,the larger is the volume fraction of Ag nanoparticles in glass after annealing.Fe2+ ion in silicate glass favors the formation of Ag nanoparticles.Ag nanoparticles size and volume fraction become larger,and plasma resonant absorption shows red-shit with increasing annealing temperature and extending annealing time.The off-resonant third-order 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.
