The electronic and optical properties of II-VI semiconductors: ZnSe, CdSe and their alloys ZnxCd1-xSe are investigated using the empirical pseudo-potential method. The energies of Γ, X and L conduction valleys of ZnxCd1-xSe alloy versus Zn fraction x are calculated. Band structure and density of states for Zn0.5Cd0.5Se are also presented. Other quantities such as the charge densities, the ionicity character, the refractive index and the transverse effective charge are also calculated.
