摘要：

首次介绍了一种新型长余辉材料 :Eu2 + ,Dy3 + 共掺杂硼铝锶长余辉玻璃陶瓷 ,该玻璃陶瓷用紫外灯、日光、荧光灯均可激发 ,发射黄绿色余辉 ,余辉的发射峰位于 5 16nm ,来自于Eu2 + 的 5d→ 8S7/ 2 跃迁。用12 0 0 0lx的荧光灯激发样品 2 0分钟 ,停止激发后 10秒时 ,该玻璃陶瓷的余辉亮度为 3 5 3cd/m2 ,色坐标为 :x =0 2 84 2 ,y =0 5 772 ;停止激发后 5小时 5 5分钟 ,该玻璃陶瓷的余辉亮度为 0 0 1cd/m2 ;停止激发 30小时后 ,余辉在黑暗中仍肉眼可见。文中对该玻璃陶瓷的相关性质进行了表征 ,并提出了可能的长余辉机理
