Solution-Processed Ultraviolet Photodetectors Based on Colloidal ZnO Nanoparticles
State Key Laboratory of Silicon Materials · Zhejiang University
Abstract
A "visible-blind" solution-processed UV photodetector is realized on the basis of colloidal ZnO nanoparticles. The devices exhibit low dark currents with a resistance >1 TOmega and high UV photocurrent efficiencies with a responsivity of 61 A/W at an average intensity of 1.06 mW/cm(2) illumination at 370 nm. The characteristic times for the rise and fall of the photocurrent are
