PREPARATION AND OPTICAL-PROPERTIES OF SEMICONDUCTOR MICROCRYSTAL-DOPED SIO2 GLASS THIN-FILMS BY RF-SPUTTERING

Semiconductor microcrystals were successfully doped in SiO2 glass thin films by an rf-sputtering. Various types of semiconductor can be doped in the films and a quantum size effect can be seen in them. For the theoretical interpretation of the effect, the influence of the matrix and the electron transition process should be taken into account. chi((3)) of the CdSe microcrystal-doped SiO2 glass film is in the neighborhood of 10(-8) esu, comparable to that of the commercial bulk filter glasses.
