Charge transfer in Pr-Doped cerium oxide: Experimental and theoretical investigations

In this study was synthesized cerium oxide (CeO2) doped with praseodymium (Pr) using a microwave-assisted hydrothermal method. The positions of the vacancies with respect to Ce3+/Ce4+ and the vacancy-like defects surrounded by the electronic density of Pr atoms were determined through photoluminesce...
