Abstract
LiPr1âxCexP4O12 (x=0, 0.002, 0.02; 0.1) powder samples were prepared using the melt solution technique. Luminescent parameters of LiPr1âxCexP4O12 phosphors have been investigated under ultraviolet-vacuum ultraviolet (3-12Â eV) synchrotron radiation and X-rays excitation at room and near liquid He temperatures. Excitation luminescence spectra of Ce3+ emission, luminescent spectra and decay curves from the lower excited state levels of the 4f15d1 and 5d1 electronic configuration of the Pr3+ and Ce3+, respectively, clearly indicate energy transfer from Pr3+ to Ce3+. Energy migration proceeds via the Pr-sublattice followed by nonradiation transfer from Pr3+ to Ce3+ ions.
