Abstract
Luminescent properties of Sr9Lu(PO4)7 crystalline powders doped with Pr3+ ions upon excitation in the ultraviolet region of the spectrum are considered. in the temperature range 5-320 K, are considered.. In the photoluminescence spectra, an intense glow corresponding to radiative interconfigurational 5d->4f-electronic transitions, weak narrow lines of intra-configuration 4f->4f-transitions, and also the emission of two types of crystal structure defects, are observed, Under pulsed electronic excitation, the temporal characteristics of emission associated with an impurity center and defects and the temperature dependence of the luminescence yield were studied. The processes of energy transfer between defects and an impurity center are discussed. Keywords: 5d->4f luminescence, energy transfer, decay kinetics, ion Pr3+
