摘要: Abstract A coupling heterostructure consisting of nickel oxide nanosheets (NNS) and titanium dioxide nanorod arrays (TNAs) was fabricated for self-powered solid-state ultraviolet (UV) photosensor applications. By controlling the thickness NNS layer by via varying growth time from 1 to 5 h at a deposition temperature 90 °C, NNS/TNAs heterojunction films were formed their structural, optical, electrical UV photoresponse properties investigated. The photocurrent measured improved increasing 140 170 nm under irradiation (365 nm, 750 µWcm−2) 0 V bias. maximum density 0.510 µA∙cm−2 achieved sample with prepared 3 h time. Our results showed that has potential applications photosensors.
