英文摘要Considering the disadvantages of the common methods for CsPbBr3singlecrystal growth including the high cost of the melt method and the low shape controllabilityof the solution method, a facile hot-pressed (HP) approach has been introduced to prepareCsPbBr3wafers. The effects of HP temperature on the phase purity of HP-CsPbBr3wafersand the performance of the corresponding photodetectors have been investigated. The HPtemperature for preparing phase-pure, shape-regular, and dense CsPbBr3wafers has beenoptimized to be 150 degrees C, and the HP-CsPbBr3wafer based planar-type photodetectorsexhibit an ultrasensitive weak light photoresponse. Under the illumination of a 530 nm LEDwith a light power density of 1.1 mu Wcm-2, the responsivity, external quantum efficiency, anddetectivity of the devices reach 19.79 A W-1, 4634%, and 2.14x1013Jones, respectively, and a fast response speed with a rise time of40.5 mu s and a fall time of 10.0 mu s has been achieved.
