Massive two-dimensional (2D) Bi 2 O 3 nanosheets (NSs) were synthesized adopting a facile solution route. It can be distinctly perceived that the average dimension of the Bi 2 O 3 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 Bi 2 O 3 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 Bi 2 O 3 NSs UVPD could perform a stable operation over a wide range of UV light intensities. Moreover, the photodetection mechanism for the Bi 2 O 3 NSs UVPD was also illustrated. • Massive two-dimensional Bi 2 O 3 nanosheets were synthesized adopting a facile solution route. • Exposure to UV light, Bi 2 O 3 nanosheets UV photodetector exhibited high photosensitivity free of the external power. • Bi 2 O 3 nanosheets UV photodetector could perform stable operation over the wide range of UV light intensities.
