Cerium is an interesting element for luminescence, however only Ce3+ ions give rise to fast luminescence because the charge transfer transition in Ce4+ is spin-forbidden. Ce-doped lutetium scandium orthoborate (Lu0.8Sc0.2BO3:Ce) has potential application in gamma-ray detection and in this Hot Article by Yuntao Wu and Guohao Ren et al. (Shanghai Institute of Ceramics, Chinese Academy of Sciences) the oxidation state of the Ce ions is investigated.
The study on single crystals of Lu0.8Sc0.2BO3:Ce utilizes XANES based on new generation synchrotron radiation. The research team were able to discover the influence cerium doping has on the luminescence mechanism and the type of point defect in Lu0.8Sc0.2BO3:Ce crystals.
