On 11 August 2025, Prof. Hai-Zheng Zhong (鐘海政), from the School of Materials Science and Engineering, Beijing Institute of Technology, visited IAPME and presented a seminal lecture titled “The Device Analysis of QLED toward Industrialization”. The talk highlighted cutting-edge research on quantum dot light-emitting diodes (QLEDs), drawing significant interest from the institute members and students. The visit was hosted by Prof. Shuang-Peng Wang.
Prof. Hai-Zheng Zhong is a leading scholar in colloidal quantum dots for photonics and optoelectronics. His current research interests are in the area of colloidal quantum dots for photonics and optoelectronics. His recent awards include the National Science Foundation for Excellent Young Scholars (2017), Beijing Science and Technology Award (2018), IDW best paper award (2019). Since 2019, he had served as senior editor for Journal of Physical Chemistry Letters, and became executive editor in 2020.
During the seminar, Prof. Zhong briefly reviewed the 30-year development history and achievements of QLED, revealing the main challenges hindering its transition from the laboratory to industrialization. He emphasized that the consistency issues caused by positive aging during operation and storage are particularly prominent. Prof. Zhong systematically summarized the research progress in QLED device analysis within the global academic community and introduced their achievements and understanding in novel analysis methods, such as transient electroluminescence, electrochemical impedance, and machine learning.
Prof. Zhong’s talk underscored the pivotal role of fundamental research in solving industrial challenges. His analytical frameworks provide a roadmap for overcoming QLED’s final barriers to commercialization. The lecture concluded with an interactive Q&A session, fostering discussions on next-generation optoelectronic materials.
During the visit, Prof. Zhong joined an IAPME lab tour, had close discussion with some professors and PhD students, and also expressed willingness to deepen cooperation.
