Abstract

Cds_xSe_1-x doped glasses are a new and developing nonlinear optical material in the 1980s^[1]. During to local field enhaned effect of small semiconductor crystallite particles in glass matrix, large optical-nonlinearity of Cds_xSe_1-x doped glass material have been shown. When ratio of surface to volume is increased by decreasing crystallite size, carrier recombination on the crystallite surfaces should be the dominant process. As a result, carrier recombination rate should be about pico-second^[2].
