Personal Introduction: In 2018, he received his PhD in Materials Science and Engineering from Nanjing University under the supervision of Professors Nie Shuming and Deng Zhengtao. From October 2018 to October 2021, he conducted postdoctoral research at the National University of Singapore under the supervision of Professor Yong Zhang. In 2022, he officially joined Nanjing Tech University and was approved for the 2024 National Natural Science Foundation of China (NSFC) Youth Fund project. He recruits 1-2 master's students annually and welcomes applicants from materials science and chemistry-related fields.
Research Interests: Controlled synthesis, photoelectric properties and stability of halide perovskite, rare-earth upconversion and heterojunction materials;
