Recently, Prof. Zang Shuangquan from the School of Chemistry, Zhengzhou University, and his crystalline molecular functional material innovation team have made new progress in the fluorescence detection and sensing of metal clusters. The relevant research，titled “Ultrafast Size Expansion and Turn‐On Luminescence of Atomically Precise Silver Clusters by Hydrogen Sulfide”, has been published in Angewandte Chemie International Edition, a leading journal in chemistry. He Weimiao, a postgraduate student from the School of Chemistry, is the first author. Professor Zang Shuangquan and Dr. Zhou Zhan of Luoyang Normal University are the co-corresponding authors. Zhengzhou University is the first corresponding unit.
