摘要：

Near-infrared (NIR) photodetector based on CH3NH3PbI3 perovskite single crystal has potential application in NIR bioimaging in the first biological window (700-900 nm). To demonstrate NIR bioimaging with the CH3NH3PbI3 single crystal photodetector, the high-performance NIR photodetector based on the CH3NH3PbI3 single crystal with the excellent crystalline quality was fabricated, the microscopic imaging system was constructed, and the in vitro NIR bioimaging of the mouse organs was performed in this work. The NIR images of the mouse kidney, mouse spleen, and mouse ovary were consistent with the corresponding real objects, indicating the feasibility of the photodetector for NIR bioimaging. The results reported in this work show that the NIR photodetector based on the CH3NH3PbI3 single crystal is expected to be widely used in bioimaging.
