Recently, the Institute of Materials Physics of the School of Physics has made progress in the field of efficient and stable perovskite luminescence research. Relevant achievements were published in Light: Science & Applications （IF: 14.00） under the title of “Water-Induced MAPbBr3@PbBr（OH） with Enhanced Luminescence and Stability”. Liu Kaikai, a young teacher of the School of Physics is the first author of the article, and Prof. Dong Lin and Prof. Shan Chongxin are the corresponding authors. This research can be applied to perovskite material systems such as methylamine lead bromide, formamidine lead bromide, cesium lead bromide, etc. It may also provide new ideas for the preparation of stable and efficient perovskite fluorescent materials, and is expected to promote the application of perovskite materials. The research work was supported by the National Natural Science Foundation of China, the China Postdoctoral Research Fund Project, and the Henan Science and Technology Research Project.
