Abstract

TiO

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

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.
