CdS microcrystal-doped glasses and Au microcrystal-doped glasses were brought into focus of the study in 1993. Following results were obtained.(1)CdS microcrystal-doped glasses ; CdS microcrystals with different controlled radii were prepared using capsulation method and embedded in SiO_2 glass by the sol-gel method. Optical obsorption edge of CdS showed so-called blue shift when the crystal radius was decreased.Fluorescence measurements were carried out for the glass composite containing nonstoichiometric cadmium sulfide particles. It was found that low energy-fluorescence which deteriorates the optical properties was ascribed to S-deficiency in the cadmium sulfide microcrystals.(2)Au-doped glasses ; Third order optical nonlinearity of the Au-doped glasses prepared from NaAlCl_4 and Si(OC_2H_5)_4 by the sol-gel method was measured by degenerate-four wave-mixing method. chi^3 value obtained by using a laser with pulse width of 6ns was 7.7X10^<-9>esu, while chi^<(3)> obtained with a laser having pulse width of picosec was 20-40% of above value. This suggests that chi^<(3)> attributable to the electron polarization is 1-3X10^<-9> esu.Au-doped Al_2O_3 and TiO_2 films were also prepared by the sol-gel method. The content of doped Au was increased in the increasing order of isoelectric point of the oxide ; SiO_2<TiO_2<Al_2O_3.

CdS微晶掺杂玻璃和Au微晶掺杂玻璃是1993年开始研究的热点。获得了以下结果。（1）CdS微晶掺杂玻璃：采用溶胶-凝胶法制备了不同粒径的CdS微晶，并将其嵌入SiO_2玻璃中。CdS的光学吸收边随着晶体半径的减小而发生蓝移。结果表明，硫化镉微晶体中的硫缺陷导致了低能量荧光，从而降低了其光学性能。（2）掺金玻璃;用简并四波混频法测量了由NaAlCl_4和Si（OC_2H_5）_4溶胶-凝胶法制备的掺金玻璃的三阶光学非线性。用脉宽为6 ns的激光测得的chi ^3值为7.7 × 10 ~<-9>（-3）esu，而用脉宽为皮秒的激光测得的chi^（3）值为上述值的20-40%。用<-9>溶胶-凝胶法制备了Au掺杂的Al_2O_3和TiO_2薄膜。掺杂Au的含量按氧化物等电点的大小依次增加：SiO_2&lt;TiO_2&lt;Al_2O_3。
