dc.description.abstract ZnO tetrapodal (t-ZnO) based photodetector has been fabricated for UV applications like wearable sensors, optical communications, pollution monitoring, etc. In this study, influence of operating temperature has been evaluated on t-ZnO based UV detectors. The structure and morphology of t-ZnO were studied using characterization tools like XRD and SEM. Photo response was evaluated at different operating temperatures from 25 °C up to 100 °C, observing maximum photo response of ~ 7178 for 400 nm wavelength at 25 ℃. The rise and fall time have been monotonically reduced ~ 496 seconds to ~ 102 seconds and ~ 1493 seconds to ~ 132 seconds in the respective tested temperature range (25 ℃ to 100 ℃). This decreasing trend of rise/fall time can be attributed to the faster desorption rate at higher temperatures. This work shows UV response decreases by increasing operating temperature in temperature range 25 ℃ to 100 ℃. This work can be extended to lower temperature ranges to evaluate its optical sensing performance in polar regions. en_US
