摘要：

The sol-gel process has been studied to prepare non-linear optics glasses doped with Cd and Zn chalcogenide microcrystals. CdS- or ZnS-doped SiO2 glasses were prepared by heat treatment of gels containing thiourea complexes of corresponding metal ions. CdSe-doped glasses were alternatively formed by immersing sol-gel-derived porous CdO-SiO2 glasses in methanol solutions of selenourea. The size of microcrystals embedded in glasses changed with the amount of thiourea complexes in gels for the sulfides and with the immersion time of the porous glasses in selenourea solutions for the selenide. Glasses containing these chalcogenide microcrystals showed quantum size effects in optical absorption spectra.
