The development of sensors that can monitor ultraviolet radiation has many implications for daily life. and even more so if the focus is on low-cost solution processes and the use of eco-friendly materials. In this study. we produced a UV-sensor based on Sn-doped ZnO thin films grown by spray pyrolysis. https://www.hindigyanvishv.com/super-find-Red-Pygmy-reg-Dogwood-Tree-limited-super/
