Biography
Professor Zhiguo Xia received his PhD degree (Inorganic Chemistry) from Tsinghua University (Beijing, China) in 2008. Since then he has been working as an assistant and associate Professor in China University of Geosciences, Beijing (CUGB), 2008-2014. After that, he has transferred and been promoted as a full professor in Beijing University of Science and Technology Beijing (USTB). He is also a committee member in the Rare Earth Phosphor and Luminescence branch of The Chinese Society of Rare Earths. His research interests covers the inorganic solid state chemistry and spectroscopic study of the rare earth doped luminescence materials. In his research, Zhiguo is very interested in designing of new rare earth phosphors for white‐LED by integrating crystal refinement and powder Rietveld refinement with experiments. In his research, he has developed several series of inorganic phosphors based on the mineral-inspired structural model and solid solution strategy, such as Ca3SiO4Br2:Eu2+, Ca2Al3O6F:Eu2+, (Na,Ca)(Sc,Mg)Si2O6:Eu2+, and so on. He has more than 120 papers on phosphors in international journals including JACS, J. Mater. Chem. C and Inorg. Chem., and has more than 2500 citations.
Research Interests
- Rare earth doped luminescence materials for white LEDs illumination and display, long lasting phosphorescence, temperature sensor, and so on.
- Quantum dots including the synthesis methodology, structural design principle and the application.
- Inorganic solid state chemistry of the functional materials, especially the crystal structure design, refinement and structure-property correlation study.
