Abstract

Massive two-dimensional (2D) Bi₂O₃ nanosheets (NSs) were synthesized adopting a facile solution route. It can be distinctly perceived that the average dimension of the Bi₂O₃ NSs was mainly centered in the range of 1–2 μm and the thickness reached about 110 nm. Afterward, the self-powered ultraviolet photodetector (UVPD) was successfully prepared established on the 2D Bi₂O₃ NSs, which exhibited high photosensitivity and robust stability in exposure to UV light, accompanied with the fast rise time of ∼33 ms and decay time of ∼47 ms. In addition, the Bi₂O₃ NSs UVPD could perform a stable operation over a wide range of UV light intensities. Moreover, the photodetection mechanism for the Bi₂O₃ NSs UVPD was also illustrated.
