摘要

A high sensitivity, fast ultraviolet (UV) photodetector was fabricated from WO_3 nanodiscs (NDs)/reduced graphene oxide (RGO) composite material. The WO_3 NDs/reduced GO composite material was synthesized using a facile three-step synthesis procedure. First, the Na_2WO _4/GO precursor was synthesized by homogeneous precipitation. Second, the Na_2WO_4/GO precursor was transformed into H _2WO_4/GO composites by acidification. Finally, the H _2WO_4/GO composites were reduced to WO_3 NDs/RGO via a hydrothermal reduction process. The UV photodetector showed a fast transient response and high responsivity, which are attributed to the improved carrier transport and collection efficiency through graphene. The excellent material properties of the WO_3 NDs/RGO composite demonstrated in this work may open up new possibilities for using WO_3 NDs/RGO for future optoelectronic applications.
