Zinc oxide thin films and zinc oxide thin films doped by chlorine, fluorine, bromine and iodine have been prepared by using the chemical spray deposition technique on a borosilicate glass. The composition and optica! properties of these thin films were studied. The results of the composition tests showed that these films are poly-crystalline and these are tangible effect of dopants on them. Optical properties include recording of the absorptance and transmittance spectra for prepared films in wave-lengths a range (330-900nm), then the energy gap in both the direct allowed and direct forbidden transitions were calculated.
