采用高温固相合成工艺制备了KSrPO4:xEu3+红色发光材料,通过X射线衍射、荧光光谱、量子效率仪、封装对发光材料的晶体结构及发光特性进行了研究。XRD表明KSrPO4晶体结构并没有随着Eu3+的掺入而发生变化;荧光光谱表明KSrPO4:Eu3+在394 nm处存在最强激发峰,发射光谱最强发射峰为612 nm;量子效率研究表明随着Eu3+掺杂量的增加,量子效率先增后降,在Eu3+掺杂量x=0.04时,量子效率存在最大值51%;封装光源的显色指数为83,色温3497 K,并且随着电流的变化色坐标(X,Y)基本保持不变,因此,KSrPO4:Eu3+红色发光材料作为近紫外激发的红色发光材料具有一定的潜力。

A red emitting material KSrPO4:xEu3+ was synthesized by high-temperature solid state reaction technology. The crystal structure and luminescence characteristic of the luminescent materials were characterized by X-ray diffraction, photoluminescence spectrum, quantum efficiency device and packaging. XRD shows that KSrPO4 crystal structure doesn't change with the incorporation of Eu3+; PL spectrum shows that KSrPO4: Eu3+ has the highest excitation peak at 394 nm and the strongest emission peak at 612 nm;the QE research indicates that with the increasing amount of Eu3+, the QE first increases and then falls, when the concentration of Eu3+(x)is 0.04,the QE reaches 51%; the color rendering index and color temperature of the packaged LED light source is 83 and 3 497 K respectively and the color coordinates (X,Y) basically remain unchanged with the changing of the current. Therefore, the red emitting material KSrPO4:Eu3+has some potential to be used as a red emitting material near ultraviolet excitation.
