ZnSe nanocrystals werein-situ grown in silica gel-glasses by using sol-gel process and the reductive thermal treatment. The transparent, homogeneous ZnSe/SiO2 nanocomposites with the yellow color were first obtained. We used X-ray diffraction pattern (XRD), UV-VIS optical absorption and Raman scattering to characterize the spectrum properties of ZnSe nanocrystals. The broadening of XRD peaks, the...
