| Abstract | ||
| In this research we study the effect of doping by cupper (10%, 20%, 30%) at the optical properties of thin films of Zinc Sulphide (ZnS) which prepared by chemical spray paralysis at pressure (1.2)bar to glass substrate at method temperature a (623)K. The optical properties studies at Visible and Ultra-volt in wavelength range (300-900)n m by using UV-visible spectrometer, the optical results show that the film have optical energy gap equal to (3.82)eV before doping and equal (2.6-2.8)eV after doping which depend on the concentration of the optical energy gap. | ||
