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.

Fluorescent lights use electricity to excite mercury vapor. This produces ultraviolet light that causes a phosphor coating inside the bulb to glow.

激发源为闪光灯泵可调谐若丹明染科激光器。

The excitation source was a flashlamp pumped Rhodamine tunable dye laser.

放电灯，亦称蒸气灯，一种照明器件，由一透明外壳构成，其中的气体被外加电压激发而发光。

Electric discharge lamp or vapor lamp: lighting device consisting of a transparent container within which a gas is energized by an applied voltage and made to glow.

So, if you use a black lamp or something and you excite something up to a higher energy level and then it relaxes back down to its lower energy state, it's going to emit a new wavelength of light, which is going to be visible to you.

如果你用一个紫外灯或别的,东西把某种分子激发到,更高的能级，然后它会掉回,到低能级，它就会释放,一个新的波长的光,这个光是可见的。
