We welcomed Prof. Tae-Woo Lee from Seoul National University as a Distinguished Visiting Scholar. On 28 July 2025, Prof. Lee delivered a seminal seminar titled “Metal Halide Perovskite for Photonics and Electronics” to a captivated audience of over 30 faculty members, researchers, and students at IAPME, the session hosted by Prof. Guichuan Xing.
Prof. Lee unveiled cutting-edge strategies to advance perovskite light-emitting diodes (PeLEDs), emphasizing their exceptional color purity and tunability critical for next-generation AR/VR displays and Rec. 2100 standards. He highlighted innovations such as guanidinium doping, bromide-based surface passivation, and core/shell nanocrystals that enhance device efficiency and stability. Revolutionary concepts like hybrid tandem PeLEDs and neuromorphic display systems— integrating perovskite LEDs with organic synaptic transistors to mimic biological neural processing—sparked vibrant discussions.
The seminar further explored ultra-stable perovskite nanocrystals achieving >95% Rec. 2020 color gamut coverage and their potential in quantum technologies, including room-temperature single-photon sources. Attendees engaged in dynamic Q&A sessions, raising insightful questions on scalability and industrial integration. The event underscored IAPME’s commitment to fostering global academic exchange. “Prof. Lee’s work bridges fundamental science and disruptive applications,” noted Prof. Xing. “His insights align perfectly with our mission to pioneer sustainable photonic technologies.”
Prof. Lee, a fellow of MRS, SPIE, and the Korean Academy of Science, holds 445 patents and has authored 300+ high-impact papers. His visit strengthens IAPME’s collaboration with Seoul National University in next-generation optoelectronics.
