• 基本释义

1.The structure of the luminophor is similar to that of MgY_4Si_3O_(13)which is recorded on the ASTM card and belongs to hexagonal system.
其结构与ASTM 卡片记载的 MgY_4Si_3O_(13)的结构相同,属于六方晶系.收藏指正
2.The preliminary luminosity of phosphorescent materials prepared at the favorable conditions above is more than 2500mcd/m2, and the luminescence after 6 hours also can be seen. The material can be easily grinded and dendity of the luminophor is low. The Sr4Al14O25: Eu2+,Dy3+ that preparaed by combustion procedure can be excited effectively by excitation light source from daylight to ultraviolet light.
用选择的优化配方及工艺制备铝酸锶铕镝发光体,所得发光体的初始亮度大于2500mcd/m2,在6h后发光体发光亮度仍人眼可辩,材料质轻、易磨,燃烧法制备的Sr4Al14O25:Eu2+,Dy3+可用日光到紫外光进行有效激发,发射光谱是一宽带谱,波峰位于520nm左右,样品发蓝绿光,属于Eu2+特征发光.收藏指正
