Abstract : Semiconductors has many characteristics and properties, such as optical properties that relates to the changes in the reflective index (n), extinction coefficient (k), single oscillator parameters, intensity, and the band gap energy. Factors that affect optical properties of semiconductor materials were investigated, ten papers that related to this topic were reviewed, in order to study these factors. It’s found that with the increase of the gamma dose, using surfactant, and using a passiveagent such as CeO2 cause a reduction in the band gap energy, while using elements from group I increase the band gap energy, annealing temperature gas no effect on the optical parameters, while preparation method of the semiconductor can effect these parameters, and using rare earth elementenhance the energy band gab.
