Fluorescence - Wikipedia

Fluorescence is the emission of light by a substance that has absorbed light or other electromagnetic radiation.It is a form of luminescence.In most cases, the emitted light has a longer wavelength, and therefore lower energy, than the absorbed radiation.The most striking example of fluorescence occurs when the absorbed radiation is in the ultraviolet region of the spectrum, and thus invisible ...
