Optical transmittance, Raman scattering, X\u2010ray photoelectron spectroscopy (XPS), grazing incidence X\u2010ray diffraction (GIXRD) and photoluminescence (PL) were used to study the grown samples. GIXRD shows the presence of the cubic phase of CdTe nanocrystals (NCs) in the silica matrix, with size ranging from 2.5 nm to 10.5 nm. Raman spectroscopy illustrates features linked to LO phonons in the CdTe structure. The absorption spectra of annealed samples demonstrate shoulders on the absorption in the range 650\u2013700 nm, in agreement with the PL emission observed at 650\u2013725 nm. However, the blue shift observed in the NCs bandgap in relationship with their size was below the expected level. We attribute this feature to the graded interface between the NCs and the matrix, which causes a weak confinement of carriers in CdTe NCs. (\u00a9 2008 WILEY\u2010VCH Verlag GmbH &amp; Co.
