摘要

研究了铈和镨共掺钇铝石榴石（YAG）荧光粉的合成及其能量传递机理。采用混合燃料燃烧法，在~500℃的炉温下合成了纯相YAG:Ce，Pr粉末。研究了YAG:Ce，Pr中Ce3+到Pr3+离子的发光光谱和能量传递机制的影响。研究了Si4+掺杂对YAG:Ce，Pr荧光粉性能的影响。在不改变峰值波长的情况下，共掺杂1 mol% Si的YAG中Ce和Pr的发射强度提高了33%，并降低了相关色温。

Synthesis, Characterization, and Optical Properties of YAG:Ce,Pr Phosphor and Influence of Si Doping

The study focuses on the synthesis and energy transfer mechanism between the cerium and praseodymium co-doped yttrium aluminum garnet (YAG) phosphors. Pure phase YAG:Ce,Pr powders were synthesized using a mixed fuel combustion method at a ~500°C furnace temperature. The luminescence spectra and the effect of the energy transfer mechanism from the Ce³⁺ to Pr³⁺ ions in YAG:Ce,Pr were examined. The influence of Si⁴⁺ doping in YAG:Ce,Pr phosphors was also studied. The emission intensity of Ce and Pr in YAG is enhanced by 33% with 1 mol% Si co-doping, without changing the peak wavelength, and it lowered the correlated color temperature.
