采用高温固相法制备了KBaPO4:Eu3+红色发光材料，研究了Eu3+掺杂浓度、电荷补偿剂等对材料发光性质的影响，并利用X射线衍射及光谱等技术对材料的性能进行了表征.研究结果显示:在400 nm近紫外光激发下，材料呈多峰发射，分别由Eu3+的5D0→7FJ(J=0,1,2,3,4)能级跃迁产生，主峰位于621 nm；监测621 nm发射峰，所得激发光谱由O2→Eu3+电荷迁移带(200~350 nm)和ff高能级跃迁吸收带(350~450 nm)组成，主峰位于400 nm；改变Eu3+掺杂浓度，KBaPO4∶Eu3+材料的发射强度随之改变，Eu3+浓度为5 mol%时，强度最大；依据Dexter理论，得知引起浓度猝灭的原因为电偶极电偶极相互作用；添加电荷补偿剂，可增强KBaPO4∶Eu3+材料的发射强度，其中以添加Li+，Cl时，材料发射强度提高最明显.

KBaPO4∶Eu3+ phosphor was synthesized by the high temperature solid state reaction method, and the effects of Eu3+ concentration and charge compensators on the luminescent characteristics of the phosphor were investigated. The phase present of the samples was characterized by powder Xray diffraction (XRD) (D/maxrA, Cu Kα, 40 kV, 40 mA, λ=0.15406 nm). The excitation and emission spectra of these phosphors were measured by a SHIMADZU RF540 fluorescence spectrophotometer. The research results show that under 400 nm excitation, the phosphor presents several emission peaks, which correspond to the 5D0→7FJ(J=0,1,2,3,4) transition of Eu3+, respectively, and the highest emission locate at 621 nm; monitored at 621 nm emission, the excitation spectrum contains 200~350 nm and 350~450 nm two excitation bands, which correspond to a weak charge transition broad band absorption CTS and a strong ff transition absorption of Eu3+, respectively, and the highest peak locates at 400 nm; the emission intensity of the phosphor was influenced by the Eu3+ concentration, and it reaches the maximum at 5 mol% Eu3+; the concentration quenching occurs when the Eu3+ concentration is beyond 5 mol%, and the concentration selfquenching mechanisms are the dd interaction by Dexter theory; under the conditions of charge compensator incorporated in the phosphor, the emission intensity can be enhanced, and can obtain the prime function with doping Li+ or Cl.
