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.

By cyclic voltammetry, electrochemical properties of the boron-doped diamond thin-film electrode were investigated compared with those of Pt/BDD electrode. It shows that the boron-doped diamond thin-film electrode has wide electrochemical window (approximate 3V), excellent chemical stability and low background current (near zero ). At the same time, the result was analyzed with energy level theory. All the works show that the boron-doped diamond thin film is a kind of ideal potential electrode.
