It is a hot point and the frontiers in materials research, and absorbs much interest because of the high nonlinear optical effect. In 1983, Jain and Lind first found that glass containing CdS<sub>x</sub>Se<sub>1-x</sub> microcrystallite exhibited high resonant nonlinear optical snsceptibility of 10<sup>-9</sup>—10<sup>-8</sup> esu with fast response time, and the size of the Cd<sub>x</sub>Se<sub>1-x</sub> microcrystallite was estimated to be about 10—100nm. Since then, more people have worked on the research of semiconductor-doped glass. In Japan, Masayuki Nagomi and the staff researched the quantum size effect and adsorption spectra of CdS, PbS, CuCl, CdTe-doped silica gel glass. Much work has been done on the semiconductor-doped glass in the Electronic Materials Research Laboratory, Xi’an Jiaotong University. A series of semiconductor microcrystallite-doped silica gel glass was prepared and the structure and properties were researched.展开更多
