| description | A facile and low-cost strategy to fabricate CsPbBr<sub>3</sub> single crystals is essential for developing perovskite optoelectronic devices. Herein, we have presented a room temperature anti-solvent precipitate method for growing sub-centimeter-sized CsPbBr<sub>3</sub> single crystals. The as-prepared CsPbBr<sub>3</sub> single crystal has an orthorhombic structure, and phase transition occurs as the measured temperature increases. The as-grown CsPbBr<sub>3</sub> single crystal also shows abundant surface morphologies including footsteps, precipitated crystals, cracks, and pits. Subsequently, a metal–semiconductor–metal (MSM)-structured photodetector was fabricated based on the CsPbBr<sub>3</sub> single crystal. Under 525 nm green light illumination, the photodetector exhibits an obvious response and the photocurrent linearly increases with the increase in the light intensity. The rise time of the photodetector increases from 0.82 s to 2.19 s as the light intensity is enhanced from 15 mW/cm<sup>2</sup> to 160 mW/cm<sup>2</sup>, indicating that more time is required to reach to a stable photocurrent. However, the decay time is as fast as ~0.82 ms, irrelevant of the light intensity. The photocurrent, under continuous light illumination, was further studied and this indicates that a stronger light intensity can accelerate the attenuation of the device. |
