Abstract
The spectroscopic characterization at low temperature was performed for undoped and Ln doped (Ln=Ce3+, Eu3+, Eu2+, Tb3+, Yb3+) Li2BaP2O7. Based on experimental data the vacuum referred binding energy (VRBE) scheme was constructed. Thermoluminescence properties were investigated and results show that the Ln-dopants do not play a role as electron traps in Li2BaP2O7. Among all investigated samples the one doped with Eu2+ exhibits the best storage properties. The thermoluminescence and fading properties of Li2BaP2O7:Eu2+ were measured and compared with that of a commercial BaFBr(I):Eu powder (AGFA). The results indicated that the produced materials have a storage capacity reaching 60% of the commercial phosphor.
