摘要

采用改进的两步高温固相熔融法制备了Yb,3+,、Eu,3+,、La,3+,共掺杂CaF,2,的上转换荧光粉。基于荧光猝灭原理，通过改变La,3+,掺杂浓度来调节CaF,2,:Yb,3+,/Eu,3+,材料的发光性能，并在980 nm近红外光激发下，获得了该材料的白色上转换发光（UCL）。在该发光体系中，Yb,3+,不仅起到了敏化Eu,3+,的作用，同时，Yb,3+,二聚体（Yb,3+,-dimer）自身合作发出波长范围480~540 nm的绿色荧光。而白光三基色中的绿光正是来自Yb,3+,二聚体的合作发光。Eu,3+,则作为激活剂，同时发出红色和蓝色荧光。荧光寿命测试结果表明Yb,3+,-dimer与Eu,3+,之间存在有效的能量传递。值得注意的是，在980 nm激光激发下，1% La,3+,掺杂的样品表现出最佳的红、绿、蓝三基色光比列，实现了材料的上转换白光发射，其色度坐标为（0.311，0.340）。

Abstract

Yb,3+, Eu,3+, La,3+, co-doped CaF,2, upconversion phosphors were synthesized by a modified two-step high temperature solid phase method. On the basis of fluorescence quenching theory, the luminescence properties of CaF,2,:Yb,3+,/Eu,3+, materials were adjusted by changing the doping concentrations of La,3+, and the white upconversion luminescence (UCL) of these materials was obtained under a 980 nm laser. In this UCL system, Yb,3+, not only sensitizes Eu,3+, but also cooperates with neighboring Yb,3+, to emit green luminescence in the wavelength range of 480-540 nm. This green luminescence just happens to be an important component of white light. In addition, Eu,3+, ions act as activators and emit both red and blue luminescence, providing two other elements in the tri-color light. Fluorescence dynamical analysis indicates that an efficient energy transfer exists between the Yb,3+,-dimers and Eu,3+, ions. It is remarkable that the white UCL can be achieved from the 1% La,3+,-doped sample, and the color coordinate is (0.311, 0.340).
