Abstract
本发明公开了一种绿色发光杂化卤化锰材料及其制备方法和应用，包括以下步骤：S1将含溴有机磷盐和溴化锰混合于丙酮溶液中，在60‑65℃下水浴加热搅拌至完全溶解，随后将混合溶液装入烧杯中；S2将烧杯在室温下静置，过滤，用丙酮洗涤，70‑80℃下干燥1‑2h后得到绿色发光杂化卤化锰材料；步骤S1中，含溴有机磷盐为(3‑溴丙基)三苯基溴化磷或(4‑溴丁基)三苯基溴化磷。本发明制备了两种具有优异发光性能的零维杂化锰基卤化物，其具有接近统一的PLQYs和可忽略的自吸收，具有非凡的辐射发光(RL)性能，产光量超过65000光子 / MeV，远远超过商用LuAG:Ce的25000光子 / MeV。
