文章采用固相法制备了硫掺杂天然方钠石的橘黄荧光粉末NaBAl6Si6O4Cl2：S2-用XRD对其结构进行了表征。研究了室温下该粉末的激发光谱，发射光谱特性。实验结果表明：在390nm激发下的发射光谱是由峰值位于626nm处的宽带谱构成，而且所得到的从500nm到800nm宽带谱归属于S2-的发光中心。在不同温度，加热时间不同的情况下，发现了硫掺杂新疆方钠石粉末的光致发光在气温900℃，加热时间30min时发光强度最佳的实验条件。

The orange-colored phosphor powder of natural sodalite codoped with S2- , NaB A16 Si6 024 CIE : S2- , were prepared by solid- state reaction method. The sample structure was characterized using XRD. The photoluminescence excitation spectra and the emission spectra at room temperature were investigated. From the experimental results, it is shown that the emission spectra consist of a broad band peaking at 626 nm upon 390 nm excitation, and the broad emission band in the range of 500--800 nm is attributed to the S2- center. The preparation conditions, such as sintering temperature and duration time, were optimized according to the strongest photoluminescence intensity of the sodalite powder in air temperature 900 ℃ heating time 30 min.
