摘要
对比了ＨＢｒ、ＨＣＩ和Ｓ气氛三种方法制备的电致发光材料的热释光曲线和老化曲线。得出结论，三种材料老化速度不同的原因是由于俘获能级的分布不同而引起的。此外，杂质的离子半径大小也影响老化速度。
In the discussion the deterioration mechanism of difference electroluminescent phosphors was discussed. By using thromoluminescence, it was found that the deterioration velocity of electroluminescent phosphors is determined by distribution of catching level. It was also showed that the deterioration velocity of electroluminescent phosphors is determined by salt halogen ion radius. The electroluminescent phosphors Were made by general way. The raw-min is fired in quartz tubes. which are surrounded by HBr, HCl or S atmosphere during flaring, respectively. We can conclude that the deterioration velocity of electroluminescent phosphors using HBr as atmosphere is slower than that at HCI and S atmosphere.
