Eu ~（2+）和Dy ~（3+）共激活的铝酸锶发光材料是一类重要的余辉发光材料。本文将该荧光粉与透明釉一起用于陶瓷表面的无机发光涂层，该涂层在高温下也是稳定的。用X射线衍射仪（XRD）和扫描电镜（SEM）分别对发光涂层的化学结构和微观结构进行了表征。用HITACHI F-4500荧光分光光度计测量涂层的光致发光。用ST-86 LA-3亮度计记录余辉性能。样品具有发光亮度高、余辉时间长等优良性能。
Phosphor of strontium aluminate co-actived by Eu2+ and Dy3+ is one kind of important afterglow luminescent materials. In this paper, the phosphors were used with transparent glaze for an inorganic luminous coating on the ceramic surface, which was stable even at high temperature. The chemical structure and microstructure of the luminous coating were identified with X-ray diffraction (XRD) and observed with scanning electron microscopy (SEM), respectively. The photoluminescence of the coating was measured by a HITACHI F-4500 fluorescence spectrophotometer. The afterglow property was recorded by a ST-86LA-3 brightness meter. The samples behaved good performances such as high lighting brightness and long after-glowing time.
