摘　　要：采用微波合成方法在不同煅烧温度、煅烧气氛下制备了Si4+掺杂的YAG荧光粉,研究了制备条件对荧光粉性能的影响。结果表明:煅烧温度和气氛对荧光粉的发光效果有重要影响。在H2/N2气氛下,随煅烧温度升高,荧光粉的发射光谱强度提高;Si4+掺杂的YAG:Ce3+荧光粉与纯的YAG:Ce3+荧光粉相比,发射光谱峰变宽,发光强度提高。Yttrium aluminum garnet（YAG） phosphors doped by Si4＋ ions were synthesized by microwave irradiation under different calcining temperatures and atmospheres.The effect of fabrication conditions on the properties was discussed.The results show that the calcination temperature and atmosphere have important effect on the luminescent properties of phosphors,and the intensity of emission spectra increases with increasing the calcination temperature under the H2/N2 atmosphere.Compared to the pure YAG：Ce3＋,the emission spectra of Si4＋ doped YAG：Ce3＋ phosphor becomes widener and its intensity increases.
