Essay

Optical spectroscopic techniques are applied for the diagnostics of formation and characterization of II-VI nanocrystals in glass matrices. The increase of heat treatment temperature or duration is shown to result in the increase of the predominant chalcogen content in CdS1-xSex ternary nanocrystals. Quaternary Cd1-yZnyS1-xSex and CdS1-x-ySexTey, semiconductor nanocrystals of two-mode and three-mode phonon spectrum transformation type, respectively, were synthesized. It is shown that beyond the optimal heat treatment parameter interval a possible alternative to the formation of CdSe-type nanocrystals is formation of Se2 clusters in the borosilicate glass.
