Luminescent properties of lithium-phosphate-borate glasses doped with Tb{3+}/Eu{3+} ions

Abstract

The luminescence of Li[2]O-B[2]O[3]-P[2]O[5]-CaF[2] scintillation glass doped Tb{3+}, Eu{3+} under different types of excitation sources are investigated. Changing the europium concentration of 0.5 to 1 wt% leads changes in luminescence intensity of Tb{3+} ions. The luminescence spectrum of the Tb3+ ions are depend on the concentration of Eu3+. It was found, that the luminescence decay kinetics of terbium ion in the band 543 nm depending on the concentration of europium and from type of excitation. The difference in the nature of the luminescence decay kinetics of glasses under pulsed photo- and electronic excitation discussed.
