Abstract

A novel high optical quality phosphate glass allowing doping with nanocrystals of CdS, CdSe, CdS_xSe_1-x solid solutions, CdTe and PbSe has been synthesized and studied. Thermal processing of the glass gives a possibility to vary both size and size distribution of the nanocrystals. High concentration of the semiconductors in the design glass provides observation of optical absorption peaks corresponding to nucleation of crystalline grains. Complicated structure of optical absorption spectra and multiple peaks related to different quantum transitions are also demonstrated for all doped glasses.
