Annealing temperature effect on the performances of porous ZnO nanosheet-based self-powered UV photodetectors.

Porous ZnO nanosheets (ZnO NSs) may play an important role in self-powered UV photodetectors due to their excellent properties, and their porosity feature affects the photoresponse performance greatly. Porous ZnO NSs were prepared by the hydrothermal method followed with a one-step annealing treatment. The effects of the annealing temperature on the microstructure and photoresponse of porous ZnO NSs and n-ZnO NSs/p-PEDOT:PSS self-powered UV photodetectors were investigated.
