摘要/Abstract

摘要： 白磷钙石结构化合物合成温度较低,且具有更加丰富可调变的晶体学格位,是一种优良的发光基质材料。本文采用高温固相法在1 250 ℃条件下合成了白磷钙石型发光材料Ca_1.8Li_0.6La_0.6-x(PO₄)₂∶xEu³⁺(x=0、0.01、0.03、0.06、0.09、0.15),并采用X射线粉末衍射仪(XRD)和荧光光谱仪对其结构和发光性能进行系统表征。结果表明,制备荧光粉均为白磷钙石结构,Eu³⁺的掺杂并未在很大程度上改变其结构。该体系荧光粉发射红光,发射光谱出现了Eu³⁺的特征发射,最强发射峰位于617 nm处,来源Eu³⁺的⁵D₀→⁷F₂跃迁。随着Eu³⁺掺杂浓度的增加,样品的荧光寿命逐渐减小,证明了Eu³⁺离子间能量传递的存在。

Abstract: Whitlockite is an excellent luminescent material. It has lower synthesis temperature and an abundance of adjustable crystal lattice.Ca_1.8Li_0.6La_0.6-x(PO₄)₂∶xEu³⁺ (x=0,0.01,0.03,0.06,0.09,0.15) was synthesized by high temperature solid state reaction at 1 250 ℃, and its structure and luminescent properties were characterized by X-ray powder diffraction (XRD) and fluorescence spectrometer. The results show that the phosphors belongs to whitlockite structure, and the doping of Eu³⁺ does not change the structure to a great extent. The phosphor in the system emits red light, and the characteristic emission of Eu³⁺ appears in the emission spectrum. The strongest emission peak locates at 617 nm and comes from ⁵D₀→⁷F₂ transition of Eu³⁺. As the concentration of Eu³⁺ increases, the fluorescence lifetime decreases, which proves the existence of energy transfer between Eu³⁺.

Key words: whitlockite, high temperature solid state method, photoluminescent property, phosphate luminescence material, red light, Eu³⁺ doping
