Abstract

ZnO thin films with grain morphology were obtained over glass substrates using the sol-gel method; these films were used as substrates to grow ZnO nanorods using chemical bath deposition (CBD) technique. The transmittance percentage of two films was over 85% and the electrical resistivity decreased when ZnO nanorods were grown over the ZnO thin film with grain morphology. A laser is incident at the thin film surface to measure the electrical response as a function of the wavelength change, it is found that electrical response is higher for the thin films with ZnO nanorods; these results shows that ZnO nanorods are a good choice for their use in photosensors.
