Influence of Annealing Temperature on the Optical Properties of Cu Doped Zinc Oxide Films

Vrushali Shelke, Mukesh Bhole

Abstract: In this work, Cu-doped zinc oxide films were deposited using the sol-gel method. The impact of annealing temperature on optical properties was examined. The transmission spectra confirm that all the samples had a percent transmission >90 in the visible wavelength range. The refractive index was found to be ~1.8 from the oscillating pattern of the transmittance spectra. It was noted that the annealing temperature has less effect on the bandgap energy, which was determined to be ~3.2 eV. SEM images and recorded EDAX spectra confirm the distribution of grains and the successful incorporation of Cu atoms in ZnO.
