摘要：
ZnO/NiO multilayer thin films were obtained using chemical bath deposition method. The precursor solution used were nickel sulphate and zinc nitrate. The effect of annealing temperature on the optical properties and band-gap energy were studied by annealing the deposited films at different temperatures of 100 degrees C and 300 degrees C. Optical properties such as absorbance and transmittance were determined using Unico UV-2102 PC spectrophotometer, at normal incidence of light in the wavelength range of 200-1000nm. The band-gap energy was discovered to lie between 2.00-2.50 eV. The composition of the deposited firm was also obtained.
