Abstract
A study of the growth of CdTe nanoparticles in novel glass system was presented. The effect of the growth of CdTe nanocrystals on the glass structure was been investigated by different techniques: differential thermal analysis (DTA), X-ray diffraction (XRD) analysis, and optical absorption spectra and FTIR spectroscopy. The evolution of X-ray diffraction at different annealing temperatures is studied and showed that the ratios of the elemental of semiconductor constituents decrease with increasing annealing temperatures. Furthermore X-ray analysis showed that the sizes of the nanoparticles increase with increasing annealing temperatures. The investigation of the absorption spectra and calculation of nanoparticles sizes from the first absorption maximum are very close to the sizes calculated by Sherrer equation. Finally, FTIR spectroscopy explained the exchangeable effects between the glass matrix and semiconductor nanoparticles during the growth of nanoparticles.
