The synthesis of Cd1-xZnxTe thin films on 7059 Corning glass substrates was described using an rf magnetron sputtering system. The band gap energy (Eg) of the samples was calculated from the photoreflectance spectra measured on the films. A 100 Watts power and time depositions of 2 hours were used for the growth an Ar pressure of 10 mTorr. The results show that the parameter b in the function Eg(x) which is called as bowing parameter is larger than the value predicted by the virtual crystal approximation (VCA) theory.
