Glass doped with semiconductor nano crystallites has been the focus of the photoelectron material science and technology for novel optical characteristics. The relationship between the absorption characteristics and composition, contents and the size distribution of nano CdSe x S 1- x crystallites embedded in boric silicate glass had been systematically studied. The results showed that the composition of CdSe x S 1- x micro crystallites have the crucial effect on the position of the cut off edge and the absorptive coefficient, and the shape of the absorption spectrum is decided by the size distribution of CdSe x S 1- x micro crystallites.
