Fluorescence

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 a lower photon energy, than the absorbed radiation. Fluorescence is the emission of light by a substance that has absorbed light or other electromagnetic radiation.

Fluorescence In Situ hybridization

It is a form of luminescence. In most cases, the emitted light has a longer wavelength, and therefore a lower photon 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 to the human eye, while the emitted light is in the visible region, which gives the fluorescent substance a distinct color that can be seen only when exposed to UV light. Fluorescent materials cease to glow nearly immediately when the radiation source stops, unlike phosphorescent materials, which continue to emit light for some time after.

Fluorescent minerals emit visible light when exposed to ultraviolet light.

Fluorescence activated cell sorting (FACS)

Fluorescence, emission of electromagnetic radiation, usually visible light, caused by exciation of atoms in a material, which then reemit almost immediately (within about 10−8 seconds). The initial excitation is usually caused by absorption of energy from incident radiation or particles, such as X-rays or electrons. Because reemission occurs so quickly, the fluorescence ceases as soon as the exciting source is removed, unlike phophorescence, which persists as an afterglow.
