Description
Summary:Lead halide perovskites have recently attracted attention due to their outstanding photoelectric properties. Hence, perovskite‐based optoelectronic devices are widely studied. Herein, a simple solution‐based one‐step anti‐solvent method to produce well‐controlled and uniform CH3NH3PbBr3‐based micro‐devices is reported. It is confirmed that the size and mode numbers of the self‐assembled microdisk cavities can be well controlled by modifying the size of the SiO2 microdisks on the substrate or changing the concentration of the perovskite precursor. With this simple and robust method, the produced CH3NH3PbBr3 microdisk arrays are extremely uniform in both their size distribution and emission spectra. Moreover, a perovskite photodetector array with fast rise (
