摘要：
Ba5-2xCexKx(PO4)3F and Ba3Ce1-xK(PO4)3F: xTb3+ phosphors were prepared by high temperature solid state method. Their structure, morphology, composition and photoluminescent properties were studied by XRD, SEM(including mapping and EDX), photoluminescence excitation and emission spectra. The results show that Ba3CeK(PO4)3F phosphor emits bright blue light under the excitation of UV light, while the emission of Ba3Ce1-xK(PO4)3F: xTb3+ phosphor gradually changes from blue light to blue green light and finally to green light as the Tb3+ doping concentration increases. The Ce3+ ions can strongly sensitize the luminescence of Tb3+ ions under UV excitation through the efficient energy transfer process from Ce3+ to Tb3+ ions. The emission intensity of Tb3+ in Ba3Ce1-xK(PO4)3F: xTb3+ reaches the maximum when the mole concentration of Tb3+ is x=0.20. © 2020, Science Press. All right reserved.
