Abstract

Ba_5-2xCe_xK_x(PO₄)₃F and Ba₃Ce_1-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 Ba₃Ce_1-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 Ba₃Ce_1-xK(PO₄)₃F: xTb³⁺ reaches the maximum when the mole concentration of Tb³⁺ is x=0.20.
