Abstract At present, the rare earth (RE) ions doped phosphors have attracted more and more attention because of their excellent properties. In this paper, a series of novel blue-purple β-Ca3(PO4)2:Ce3+ phosphors were synthesized by a high temperature solid phase method. The X-ray diffraction (XRD), infrared spectrum, energy dispersive spectroscopy (EDS), scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS), photoluminescence excitation and emission spectra were used to investigate the crystal structure, composition and the luminescent properties of the resulting samples. The phosphor shows a strong absorption in the ultraviolet band. Under the excitation of 269 nm, the phosphor emits a strong purple fluorescence ranging from 360 to 520 nm. When Ce3+ doping content is 0.07 mol, the strongest luminescence intensity is reached, and the concentration quenching mechanism is dipole-dipole (d-d) interaction for Ce3+ based on Dexter theory.

一种新型的蓝紫色 Ce3+ 掺杂白云石磷光体：合成、晶体结构和光致发光特性

摘要 目前，稀土（RE）离子掺杂的荧光粉因其优异的性能而受到越来越多的关注。本文采用高温固相法合成了一系列新型蓝紫色β-Ca3(PO4)2:Ce3+荧光粉。X 射线衍射 (XRD)、红外光谱、能量色散光谱 (EDS)、扫描电子显微镜 (SEM)、X 射线光电子能谱 (XPS)、光致发光激发和发射光谱用于研究晶体结构、成分和所得样品的发光特性。磷光体在紫外波段表现出强吸收。在 269 nm 的激发下，荧光粉发出 360 至 520 nm 范围内的强烈紫色荧光。当Ce3+掺杂量为0.07 mol时，达到最强发光强度，
