- W67134022 abstract "采用传统的高温固相法合成了蓝色长余辉发光材料Sr2Al6O11∶Eu2＋,Dy3＋,系统研究了烧结温度对Eu2＋和Dy3＋共掺杂蓝色铝酸锶长余辉材料物相及发光性能的影响。用X射线衍射仪对所合成的材料进行物相分析,用荧光分光光度计记录了样品的激发光谱和发射光谱,用亮度计记录其余辉衰减曲线。结果表明：随着烧结温度从1100℃升高到1300℃,材料的物相由富锶相逐渐向富铝相转变,其中1200℃条件下合成的样品主相为Sr2Al6O11;发射光谱首先发生蓝移,随后又发生红移,其中1200℃条件下合成的样品发射光谱峰值波长最短（468 nm）;主相为Sr2Al6O11的蓝色铝酸锶长余辉材料的余辉时间（≥1 mcd/m2）可达240 min以上。" @default.
