Abstract

We have measured and analyzed optical absorption, Raman scattering and x-ray absorption spectra of CdS nanocrystals grown by solid-state reaction in a borosilicate glass. We observe the appearance and growth of an optical absorption peak which is attributed to CdS nanoparticles. Using x-ray absorption we quantify the progressive replacement of O nearest neighbors of Cd by S with heat treatment and the appearance and growth of a well-defined second nearest neighbor peak.
