Quantum dots are a class of semiconductor nanocrystals with a diameter ranging from 2 to 20 nm. Because of quantum confinement effects, quantum dots exhibit physical-chemical properties very different from those of the corresponding bulk materials, and they find wide applications in fluorescent labelling, quantum light emitting diode (QLED) technology, solar cell manufacture and so on. The Royal Swedish Academy of Sciences announced that the 2023 Nobel Prize in Chemistry was awarded to Moungi G. Bawendi, Louis E. Brus and Alexei I. Ekimov for their pioneering contribution to the discovery and synthesis of quantum dots.
Jiesheng Chen graduated from Sun Yat-Sen University with a BSc degree (1983) and a MSc degree (1986), and from Jilin University with a PhD degree (1989). In 1990, he moved to the Royal Institution of Great Britain in the UK as a postdoctor. He returned to Jilin University in 1994, joining the faculty of the Chemistry College where he was promoted to a full professor later on. In 2008 he joined the faculty of the School of Chemistry and Chemical Engineering at Shanghai Jiao Tong University. His research has been focused on inorganic synthesis and solid state materials chemistry, and he has published more than 400 scientific articles so far. He obtained the National Outstanding Young Scholar fund in 1997 and the Changjiang Professorship in 1999. He was also awarded the Shanghai Municipal First Prize in Natural Science，the First Prize in Natural Science of the Education Ministry and the National Second Prize in Natural Science. Professor Chen is a Fellow of the Royal Society of Chemistry (FRSC) and an Advisory Board Member for J. Mater. Chem. A, Mater. Adv. and a few other journals.
