摘要：

TiO 2 nanotubes arrays were fabricated on ITO substrate via a liquid phase deposition method, with the assistance of ZnO nanorods arrays template, and the morphologies and structures of the samples were characterized by using SEM and XRD. Furthermore, the photoelectrochemical photodetector was fabricated with ITO as counter electrode and the photocurrent and spectral responses were measured. In addition to the high sensitivity and self-powered characteristic, the photodetector also revealed a splendid wavelength selectivity in the spectral range between 300 and 400 nm at zero bias voltage. Meanwhile, it is interesting to note that self-powered TiO 2 nanotubes UV-photodetector has the excellent stability and repeatability, and the rise time and decay time are 0.33 s and 0.38 s, respectively. © 2018, Science Press.
