Biography: 
Lei Chen who was born in 1977 is a professor at Hefei University of Technology. He got his Ph.D. from University of Science and Technology of China in 2007, majored in Nuclear Science and Applications. He was engaged in postdoctoral research at National Taiwan University in Taiwan and took visiting-professor at University of Alberta in Canada. His research interests focus on solid-state inorganic chemistry, crystal and electronic structures of inorganic compounds, condensed-mater physics, solid-state luminescence and luminescence physics, synchrotron radiation technology and application, phosphors for light-emitting diodes (LED), and quantum dots for display. By employing experiment approaches of extended X-ray absorption fine structure spectroscopy (EXAFS), X-ray and neutron diffractions, a Eu3+ spectroscopic probe, etc., and theoretical approach of First-Principles calculations, Prof. Chen has made great achievements on understanding electronic and crystal structures of solid-state inorganic compounds. He and his group discovered the phenomenon local symmetry breaking in crystal structure of Li2SrSiO4 with reduced local symmetry (Adv. Sci. 2019, 6, 1802126), observed the exceptionally local expansion of Eu-N bonding in crystal lattice of CaAlSiN3:Eu with the shift of Fermi level and the change of Fermi-Dirac distribution of electrons on excited sub-states (Chem. Mater. 2016, 28, 5505), and found the disappearance of charge-transfer band and the non-radiative transition from absorption spectra after exfoliating g-C3N4 powder to form quantum dots (Materials Today, 2019, 22, 76). Prof. Chen has published 65 peer-reviewed papers with h-index 29. Due to his great contributions, Prof. Chen was awarded with a Third-Class and a Second-Class Science and Technology Prize of Anhui province in 2009 and 2018, respectively, by the government of Anhui Province of China and awarded with a Second-Class Science and Technology Prize of Guangdong province in 2019 by the government of Guangdong Province of China.
