This method achieves precise spatial control over multipoint crystallization in perovskite, indicating advances for optoelectronic devices.
In this study, we present a method for reconfigurable multipoint crystallization of lead halide perovskites using digital holographic optical trapping. By combining computer-generated holograms and optical trapping-induced crystallization method, precise spatial control over multipoint perovskite crystallization is achieved and the crystallization positions can be adjusted, enabling the creation of reconfigurable and dynamic multipoint crystallization arrays within the solution. These findings offer a new method for advancing the fabrication and engineering of perovskite crystal arrays for optoelectronic devices.
