Fabrication and Characterization of Ultra Violet Photosensor based on Single ZnO Nanorod

This article presents the fabrication and characterization of ultra violet (UV) photosensor, which utilizes the semiconducting properties of single ZnO nanorod. We report a study on the ZnO nanorods synthesized by an aqueous solution route in a hydrothermal reactor. Samples were characterized by X-ray diffraction, scanning electron microscopy, optical and electrical studies. Our cost-effective synthesis method for ZnO nano/microrods permits easy transfer of sample and allows the study of fabrication of novel electronic nanodevices, such as gas and UV nanosensors. Our work is a starting point on the nanofabrication of optoelectronic nanodevices. It is anticipated to have a wide range of applications in space research, warning systems and accurate measurement of UV radiation.
