AbstractEu3+-activated La2CaB10O19 phosphors with nominal chemical formulae La2-xEuxCaB10O19 and La2Ca1-2xEuxNaxB10O19 were prepared. The luminescence properties under VUV-UV excitation were investigated. Luminescence spectra reveal Eu3+ ions occupy both Ca2+ and La3+ sites in all samples. The O2- -> Eu3+ charge transfer bands (CTBs) and the D-5(0) -> F-7(0) emissions of Eu3+ at Ca2+ site and La3+ site are identified, respectively. The schematic energy levels for Eu3+ in two sites were achieved. Luminescence decays of the D-5(0) -> F-7(0) transitions were measured for both sites.
