This paper reports the luminescence behavior of Sr Al O :Eu ,Dy phosphors under UV-irradiation. The effect of UV-irradiation on afterglow (AG), thermoluminescence (TL) and mechanoluminescence (ML) of Sr Al O :Eu ,Dy phosphors is investigated. The space group of Sr Al O :Eu ,Dy phosphors is monoclinic P2 . The prepared phosphors exhibit a long AG, intense TL and ML. It is found that the AG, ML intensity and TL increase with increasing duration of irradiation time. The ML intensity decreases with successive impact of the load onto the phosphors, whereby the diminished ML intensity can be recovered by UV-irradiation. Copyright © 2016 John Wiley & Sons, Ltd.
本文报道了SrAlO:Eu,Dy荧光粉在紫外光照射下的发光行为。研究了紫外光照射对SrAlO:Eu,Dy荧光粉余辉（AG）、热释光（TL）和机械发光（ML）的影响。SrAlO:Eu,Dy荧光粉的空间群为单斜P2。制备的荧光粉表现出长余辉、强热释光和机械发光。发现余辉、机械发光强度和热释光随照射时间的增加而增加。机械发光强度随着负载对荧光粉的连续冲击而降低，通过紫外光照射可以恢复降低的机械发光强度。版权所有©2016约翰威立父子有限公司。
