1. The fluorescent material which coats the screen of a CRT. When the electron beam strikes the phosphor its electrons become excited and move to a higher energy level. When the electrons return to their original level they give off thelight that forms the display on the screen. 
   涂在阴极射线管（crt）屏幕上的荧光材料。当电子束打到它上面，激活它的电子到较高的能级上，等电子返回到它原来的能级时便发出光，使屏幕上显示出图象。
2. On either side of the phosphor layer is a conducting layer, which provides electrons and creates the electric fields that drive the electrons onto the phosphor. 
   荧光粉层的一边是一导电层，它提供电子形成电场，此电场驱使电子飞向荧光粉。
3. The emission of light from a phosphor after removal of excitation. 
   余辉激振停止后的磷光物质所发出的光
4. The plant of growth needs three kinds of elements: nitrogen, phosphor and potassium. 
   生长着的植物需要三种元素：氮、磷、钾。
5. Electroluminescent (EL) displays produce light when electrons hit a phosphor layer sandwiched between two insulating layers. 
   在场致发光（el）显示器中，当电子击中夹在两层绝缘层中间的荧光粉层时就产生光。
