1·Fluorescent lights use electricity to excite mercury vapor. This produces ultraviolet light that causes a phosphor coating inside the bulb to glow.
荧光灯用电激发水银蒸气。这会生成紫外线光而使得镀在灯管内壁上的磷涂层发光.
2·Excited by the current, the mercury atoms emit ultraviolet light, which bombards the phosphor coating on the inside of the tube.
被电流激活后，汞原子发出紫外光，轰击被覆在电子管内部的磷。
3·The simplest and most common way is to coat a blue LED with a yellow phosphor.
最简单也最普通就是在蓝色LED上罩一层黄色的磷。
4·This strikes the phosphor on the glass walls and makes it glow brightly.
当管壁上的磷粉碰到紫外线时，便能产生明亮的辉光。这就是荧光管的原理。
5·These can be made to emit white light by coating the device with a phosphor compound that absorbs part of the blue light and re-emits it as yellow.
只要为发光装置加上磷化合物涂层，吸收蓝光，重新发出的光线即呈黄色。
