Abstract
The nanosized [Sb.sub.2]S.sub.3 doped silica glasses were prepared by the sol-gel method and the maximum dopant of [Sb.sub.2]S.sub.3 dissolvable in the silica is 7wt.%. XRD, HRTEM and FTFIR measurements indicated that the nanocrystal was formed in the matrix. The red shift with the increasing of the annealing time and temperature was observed by the transmission spectra measurements of the bulk, which was due to the quantum size effect. Second harmonic generation was also observed in the glasses irradiated by electron beam. The SH intensity of the sample was about four times larger than that of quartz as a reference.
