Abstract:This paper reports the spectroscopic properties of phosphates KLuP2O7, Sr9Sc(PO4)7, K3Lu(PO4)2, doped with Pr3+ ions. Photoluminescence (PL) spectra under selective excitation with UV photons, PL excitation spectra, and decay kinetics of pulsed cathodoluminescence are studied. Recordings of luminescence spectra were done with non-irradiated samples and after their irradiation with fast electrons (E = 10 MeV) or fast reactor neutrons. Three typical channels of electronic excitations radiative relaxation have be… Show more
