摘要: 通过高温固相法合成了一种颜色可调的荧光粉KBaPO4:Ce3+,Tb3+,并对其微观结构、光致发光、能量传递机理和浓度猝灭机理进行了探究。由于Ce3+,Tb3+KBaPO4基质中发生了有效的能量传递,大大增强了荧光粉中Tb3+离子的发光强度,通过改变Tb3+的浓度,实现了KBaPO4:Ce3+,Tb3+荧光粉的发光颜色从蓝色向蓝绿色到绿色的调控。研究结果表明,KBaPO4:Ce3+,Tb3+的浓度猝灭原因是由于偶极偶极相互作用。

Spectral Control of KBaPO4: Ce3+, Tb3+Phosphors by Energy TransferJIAO Yanmei, LIU Jie

(College of Chemistry and Molecular Engineering, Qingdao University of Science and Technology, Qingdao 266042, China)Abstract: A colortunable phosphor KBaPO4:Ce3+, Tb3+was synthesized by conventional solid state reaction method. The microstructure, photoluminescence, energy transfer mechanism and concentration quenching mechanism were investigated.The emission intensity of Tb3+ is enhanced greatly by the energy transfer from Ce3+ to Tb3+. The emission colors of KBaPO4:Ce3+, Tb3+ phosphor can be adjusted from blue tobluegreen to green by changing Tb3+ concentration.The results suggest that the concentration quenching of KBaPO4:Ce3+, Tb3+ was due to the dipoledipole interaction.

Key words: phosphor; spectral control; energy transfer; high temperature solid state method
