Biography
François Cheviré received a Master (2001) and a Ph.D. (2004) in Solid State Chemistry from the University of Rennes 1, France. After conducting postdoctoral reasearch at the Chemistry and Chemical Biology Department at Cornell University, Ithaca NY (2005–2006) under the supervision of Pr. Francis J. DiSalvo and at the Mistubishi Chemical – Center for Advanced Materials (MC-CAM) at the University of California, Santa Barbara CA (2006–2007) under the supervision of Pr. Anthony K. Cheetham, he joined the CNRS as a research fellow in 2007 and is pursuing research on new nitrogen containing inorganic materials as phosphors, photocatalysts and optoelectronic materials in the Glass and Ceramics group of the Institute of Chemical Sciences of Rennes (ISCR). In 2017, he received his Habilitation to supervise research (HDR) in Chemistry from the University of Rennes 1.
Current Themes of Research
Physicochemistry of mixed anions materials (O, N, S, NCN) and related materials Development of novel synthesis routes to nitrogen containing materials Additive manufacturing of glass materials Oxynitride thin films Structural Charaterizations on powders Optoelectronics properties Environmental and Energy related materials: visible-light photocatalysis, phosphors, p-type semiconductors.
