LANTHANIDE – DEFECTS INTERACTIONS IN CERIA PROBED BY LUMINESCENCE SPECTROSCOPY
WG3 members: Carmen Tiseanu, Daniel Avram
The broad aim of our research is to investigate the structure – luminescence relationships occurring in lanthanide doped CeO2 materials. Our approach is based on the unitary investigation of their luminescence and structural properties. We use a broad range of experimental techniques based on room and low temperature luminescence with spectral and temporal resolution, excited state dynamics and excitation spectra. In collaboration with University of Bucharest and several international groups, we correlate the luminescence properties with the structural data obtained by use of in situ / ex situ X-ray diffraction and Raman spectroscopy, DRIFTS, HRTEM, etc.
