Abstract: ZnO thin films (thickness ~441nm, crystal size ~19.6nm) were synthesized by a single deposition method using zinc-ammonia complex as main precursor. Effect of synthesis temperature on the morphology and phase purity crystallization was studiesdat three different temperatures (70, 80 and 90 °C)for fixed time (20 sec)using microwave oven. Phase identification, morphology and structural properties of the ZnO thin films were studied using diffraction, microscopic and spectroscopic techniques. The ZnO thin films prepared at 70ºC show amorphous character while 90ºC films are crystalline as indicated by sharp diffraction peak in X-ray diffraction (XRD) pattern. Moreover, the surface morphology of the ZnO thin films strongly depend on deposition temperature. The optical characteristics of the samples were obtained by UV-Visible spectrophotometer at 200–900 nm wavelengths. The absorption at wavelength <370 nm indicates that the nano size ZnO nanoparticles have band gap energy of ≈3.4eV.
