主讲人/Speaker

Xiaogang Peng is currently a Professor at Zhejiang University. Before moving back to China in 2009, he was on the faculty at the University of Arkansas as Assistant Professor (1999-2003), Associate Professor (2003-2005), and Professor with Chair (2005-2009). He received his B.S. (1987) and Ph.D. (1992) from Jilin University, China. His Postdoctoral experience followed by a position as Staff Scientist at UC Berkeley between 1994 and 1999 brought him into the field of colloidal nanocrystals. Shortly after starting his tenure at the University of Arkansas in 1999, he founded NN-Labs LLC in USA to explore industrial applications of quantum dots. In 2009, he founded Najing Tech Corporation in Hangzhou, currently focusing on quantum-dot display technologies.


讲座摘要/Abstract:

Colloidal quantum dots (QDs) are unique optical and optoelectronic materials for various applications, such as optimal emitters for display because of their size-tunable yet ultra-narrow emission. With ~20 years efforts, QDs can now be synthesized with monodisperse size/shape distribution, near unity emission quantum yield, and high chemical/optical stability, but their optical and opotoelectronic properties are still largely a puzzle. One fundamental reason is that it would be impossible to reliably predict their excited-state properties based on their ground-state properties. The second fundamental reason tight entanglement of their photophysical and photochemical properties.  Thirdly, both photophysical and photochemical properties of QDs strongly depend on their poorly-defined interface structure.  This talk shall discuss an attempt to discover clues to the puzzle by intentionally correlating photochemical and photochemical properties of QDs.
