- W2146021929 abstract "The excitation and emission properties of ${mathrm{Pr}}^{3+}$ and ${mathrm{Ce}}^{3+}$ doped $M{mathrm{SO}}_{4}$ ${(M}^{2+}={mathrm{Ca}}^{2+},$ ${mathrm{Sr}}^{2+},$ and ${mathrm{Ba}}^{2+})$ were investigated at 293 and 10 K. The lowest $5d$ level in ${mathrm{CaSO}}_{4}:{mathrm{Pr}}^{3+}$ is located below the ${4f}^{2}{[}^{1}{S}_{0}]$ level resulting in allowed $4f5stackrel{ensuremath{rightarrow}}{d}{4f}^{2}$ transitions. In ${mathrm{BaSO}}_{4}$ and ${mathrm{SrSO}}_{4}$ the lowest $5d$ level appears above the ${}^{1}{S}_{0}$ level and ${4f}^{2}{[}^{1}{S}_{0}stackrel{ensuremath{rightarrow}}{]}{4f}^{2}$ emission is observed. However, also $4f5stackrel{ensuremath{rightarrow}}{d}{4f}^{2}$ emission occurs, suggesting the presence of two different Pr centers. The unusual temperature dependence of the emission, points, however, to a thermal excitation process from the ${}^{1}{S}_{0}$ state to the $4f5d$ states involving only one site. The internal quantum efficiency of the ${}^{3}{P}_{0}$ and ${}^{1}{D}_{2}$ emission in ${mathrm{BaSO}}_{4}$ is estimated to be 0.1 and 1 %, respectively. It will be demonstrated that under host lattice excitation part of the energy is transferred to ${4f}^{2}$ states with lower energy than the ${}^{1}{S}_{0}$ or the $4f5d$ states. The possibility for quantum splitting to occur in ${mathrm{Pr}}^{3+}$ doped oxides and fluorides will be discussed. Trends observed in the interaction between the crystal field and the $5d$ electron of ${mathrm{Ce}}^{3+},$ will be applied to predict the energy of the $4f5d$ states of ${mathrm{Pr}}^{3+}.$" @default.
