Synthesis of Ag-Doped ZnO Nanostructured Films for UV Photodetectors

Abstract

In this work, the Ag-doped ZnO nanostructured films were successfully synthesized via a simple chemical solution based method (SCS). The influence of post-growth thermal annealing, namely rapid thermal annealing (RTA) and conventional thermal annealing (TA) in electrical furnace on the UV sensing properties were investigated. The increase in UV sensing properties by doping with Ag, as well as by applying post-growth annealing was observed. The optimal Ag content was found to be ~ 0.95 wt%, while the optimal RTA regime is 725 °C for 60 s
