Abstract: Zinc oxide is a wurtzite structure semiconductor with piezoelectric and piezophototronic properties. This material has an energy band gap of 3.37 ev, high excitation energy and near- ultraviolet emission. The special properties of this material have led to various applications including optical detectors and optical sensors, that has provided many research fields. In this research, initially, the sputtering process was used to deposit ZnO on the flexible PET/ITO substrate. Then, the created thin layer was deposited under a certain temperature and time for the growth of zinc oxide nanorods by hydrothermal method. Also, silicon dioxide nanospheres have been deposited on the substrates using deep coating and spin coating methods, and in order to eva‎luated the optical and structural properties, ultraviolet- visible spectroscopic analysis and FESEM have been used. Finally, in current research, we have tried to achieve more absorption and ultimately more efficiency for optical detectors by above-mentioned methods.
