Professor Xiaogang Peng stands as a distinguished leader in the field of nanomaterials chemistry and quantum dot research at one of China's premier academic institutions. He currently serves as a Full Professor and Doctoral Supervisor in the Department of Chemistry at Zhejiang University, where he has established a world-class research program since joining the faculty in 2009. Dr. Peng received his foundational education at Jilin University, completing his Bachelor of Science degree in 1987 followed by his Ph.D. in 1992, demonstrating exceptional promise early in his academic journey. Prior to his return to China, he gained valuable international experience as a faculty member at a university abroad, building expertise that would later inform his groundbreaking contributions to nanomaterials science. His leadership in the Department of Chemistry has positioned Zhejiang University as a global hub for cutting-edge research in colloidal nanocrystals and quantum dot technologies.
Professor Peng's pioneering research program has fundamentally advanced the synthetic chemistry and spectroscopic understanding of colloidal quantum dots, establishing new paradigms in nanomaterial design and characterization. His seminal work on phonon-assisted up-conversion photoluminescence of quantum dots, published in Nature Communications in 2021, represents a significant breakthrough in manipulating light-matter interactions at the nanoscale. His innovative approaches to enhancing dielectric screening for Auger suppression in CdSe/CdS quantum dots through epitaxial growth of ZnS shells have opened new pathways for improving quantum efficiency in optoelectronic applications. Professor Peng's research integrates sophisticated synthetic methodologies with advanced spectroscopic techniques to unravel the complex photophysical properties of nanocrystals, contributing to the fundamental knowledge base that underpins next-generation optoelectronic devices. His contributions to deciphering charging status, absolute quantum efficiency, and absorption cross-section of multi-carrier states in single colloidal quantum dots have provided critical insights for the development of high-performance quantum dot technologies.
Beyond his individual research achievements, Professor Peng has cultivated a vibrant research ecosystem at Zhejiang University that attracts talented scientists from around the world and fosters interdisciplinary collaboration across chemistry, physics, and materials science. His research group has produced numerous high-impact publications in leading journals including Nature Communications, Nano Letters, and other prestigious venues, establishing him as a central figure in the global quantum dot research community. Professor Peng has mentored a generation of researchers who have gone on to establish their own successful careers in academia and industry, including notable scholars like Dr. Haiyan Qin who has advanced the application of single-molecule microscopy and transient fluorescence spectroscopy to study nanocrystal properties. His work continues to drive innovation in quantum dot technologies with promising applications in displays, sensing, and renewable energy technologies. As the field of nanomaterials continues to evolve, Professor Peng remains at the forefront of research, guiding future directions that bridge fundamental science with practical applications that could transform multiple technological domains.
