RESUMO

Graphene-structure WSe2 nano-films (NFMs) were prepared by magnetron sputtering and vacuum selenization. The as synthesized WSe2 NFMs were characterized using various techniques such as SEM, XRD and EDS. Our work provides a simple and effective method to prepare WSe2 NFMs. We have observed the high photo responsivity of WSe2 NFMs up to 10 A W-1, which is 40% higher than the previously reported data. Our photoelectrochemical tests demonstrate that WSe2 NFMs have excellent photoelectric properties, indicating that NFMs have a wide application potentialsin solar cells and optoelectronic devices.
