Abstract
We demonstrate synthesis and crystallization of lead halide perovskites under the focused laser irradiation in the unsaturated precursor solutions. Upon the irradiation onto the air/solution interface, a perovskite crystal is formed from the focal spot. The synthesized crystal collects more precursors and grows large while trapped at the focus. The formed crystal dissolves after the laser turns off, which is due to unsaturated condition of the surrounding solution. The mechanism of the crystallization is discussed from the viewpoints of laser heating and laser trapping.
