Abstract

Abstract: Nanoparticles of hybrid organic–inorganic perovskites have attracted a great deal of attention due to their variety of optoelectronic properties, their low cost, and their easier integration into devices with complex geometry, compared with microcrystalline, thin‐film, or bulk metal halides. Here we present a novel one‐step synthesis of organolead bromide perovskite nanocrystals based on pulsed‐laser irradiation in a liquid environment (PLIL). Starting from a bulk CH3 NH3 PbBr3 crystal, our PLIL procedure does not involve the use of high‐boiling‐point polar solvents or templating agents, and runs at room temperature. The resulting nanoparticles are characterized by high crystallinity and are completely free of any microscopic product or organic coating layer. We also demonstrate the straightforward inclusion of laser‐generated perovskite nanocrystals in a polymeric matrix to form a nanocomposite with single‐ and two‐photon luminescence properties. Abstract : Better with lasers ! The one‐step synthesis of "clean" and crystalline organolead halide perovskite nanocrystals by using pulsed‐laser fragmentation in a liquid environment is demonstrated. This procedure does not involve high‐boiling‐point polar solvents or templating agents, and is performed at room temperature.
