摘要

利用高温固相法制备了一系列Li+、Bi3+掺杂Lu2O3∶Ho3+荧光粉体。研究结果表明，不同摩尔分数Li+、Bi3+与Ho3+的掺入不改变Lu2O3的立方相结构；与Lu2O3∶2%Ho3+样品相比，16%Li+掺杂、1.5%Bi3+掺杂以及2%Li+与1.5%Bi3+共掺样品的发光强度分别提高了3.0,128.9,1.4倍;而在449 nm波长激发下，三个样品的荧光寿命均有不同程度的缩短。

Abstract

A series of Li+, Bi3+ co-doped Lu2O3∶Ho3+ phosphors are prepared by the high temperature solid-state method. The research results show that the doping of Li+, Bi3+ and Ho3+ with different mole fractions does not change the cubic phase structure of Lu2O3. Compared with that of Lu2O3∶ 2%Ho3+ sample, the luminescence intensities of the three kinds of samples doped with 16%Li+, 1.5%Bi3+, 2%Li+/1.5%Bi3+ increase by 3.0, 128.9, 1.4 times, respectively. However, the fluorescence lifetimes of these three kinds of samples under the excitation of a laser with a wavelength of 449 nm are shortened by different degrees.
