Abstract：The phosphors of 2SrO·0.84 P2O5·0.16 B2O3: RE3+(RE=Ce，Tb) were synthesized by high temperature solid state reaction.The luminescence properties of Ce3+, Tb3+ and the sensitization of Ce3+ to Tb3+ were studied.In the excitation spectrum of Ce3+, there are two broad bands at 232 and 296 nm respectively.Because of the large overlap between the emission bands, the authors could not separate them from each other.The authors could get two bands at 325 and 344 nm with the Gaussian fitting method.The possible reason is that these two peaks are from two light centers.In the phosphor of 2SrO ·0.84 P2O5·0.16 B2O3: Tb3+, the excitation spectrum of Tb3+ exhibits high absorption at 370 nm and emission spectrum shows the strongest emission peak at 548 nm.The emission from the levels of 5D3 and 5D4 of Tb3+ appear at the same time, indicating that non-radiative process between them is inefficient.In the phosphor of Ce3+ and Tb3+ co-doped 2SrO·0.84 P2O5·0.16 B2O3, efficient energy transfer exists.
