专利号:WO-2025062384-A2 优先权日:2023-09-23 标题 :A method for synthesis of metal halide perovskite (cspbbr3) nano/microcrystals 发明人:M A GOKUL; RAHMAN ATIKUR 权利人:INDIAN INSTITUTE OF SCIENCE EDUCATION AND RES PUNE IISER PUNE 摘要:The present invention relates to metal halide perovskite (CsPbBr3) nano/microcrystals. Specifically, the present invention relates to a method for the synthesis of metal halide perovskite (CsPbBr3) nano/microcrystals. The present invention uses an easy, scalable low temperature growth of metal halide nanoparticles like CsPbBr3. The method uses a clever play on the solubility and ion exchange mechanism to precipitate nano and microcrystals of metal halide perovskites. The synthesis resulted in stable perovskite crystals with high photo- luminescence, ultralow dark current and control over their morphology. The combination of ultralow dark current, high responsivity, exceptional detectivity, and broad-band photon detection capabilities makes these crystals an excellent choice for upcoming sensors and detector technologies.

The catalytic activity of the Group 13 metal alkoxide adduct compounds is useful for the ring opening polymerization (ROP) of compounds such as racemic lactide to yield PLA. These Group 13 metal alkoxide adducts initiate polymerization under milder reaction conditions as compared to tin octanoate and thus can serve as catalyst for synthesis of polymers like PLA,Polycaprolactone with 10 high molecular weight.
