It is observed that the absorption edge of the CdS/SiO2 shifts in comparison with that of the bulk CdS as the annealing temperature change as well as the loading of CdS in SiO2.

It is observed that the absorption edge of the ZnS/SiO_2 shifts in comparison with that of the bulk ZnS as the annealing temperature change as well as the loading of ZnS in SiO_2.

However, the absorption edge of Zn∶LiNbO 3is blue-shifted with increasing Zn dopant.

UV-VIS absorption spectrum and its derivative of absorption spectrum were used to detemine the shift of band-edge of optical absorption and band gap value along with the variation of temperature.
