Abstract

Ag nanoparticles (NPs) have been successfully deposited onto TiO2 nanotubes (NTs) via a photochemical method and ZnS layer was further fabricated on the surface of the TiO2/Ag NTs at room temperature. The morphology, composition and structure of the as-prepared samples were analyzed. A self-powered UV photodetector (UVPD) based on the TiO2/Ag/ZnS NTs has been constructed. When exposed to UV light, the TiO2/Ag/ZnS NTs UVPD manifests a higher photocurrent density than that of the TiO2 and TiO2/Ag NTs UVPDs at a bias of zero V. The TiO2/Ag/ZnS NTs UVPD also reveals a splendid linear optical signal response. Meanwhile, it is noteworthy that the TiO2/Ag/ZnS NTs UVPD has excellent stability and repeatability, and the rise time and decay time are 0.16 s and 0.18 s, respectively. Moreover, a possible UV detection mechanism of the TiO2/Ag/ZnS NTs UVPD is proposed.
