Enhanced photocurrent of a ZnO nanorod array sensitized with graphene quantum dots

Abstract

In this communication, we demonstrate a facile method to prepare a graphene quantum dots (GQDs) decorated ZnO nanorod array (ZNRA) ultraviolet detector. The characterization of IV and time-dependent current behaviors under UV light illumination show that, although GQDs have little influence on the dark conductivity of ZNRA, the coating of GQDs has a remarkable sensitization effect on the photocurrent of ZNRA. This enhancement of the photocurrent was due to the interfacial charge transfer from GQDs to ZNRA.
