Fluorescent minerals emit visible light when exposed to ultraviolet. Fluorescent marine organisms Fluorescent clothes used in black light theater production, Prague. Fluorescence is one of two kinds of emission of light by a substance that has absorbed light or other electromagnetic radiation.
A fluorescent lamp, or fluorescent tube, is a low-pressure mercury-vapor gas-discharge lamp that uses fluorescence to produce visible light. An electric current in the gas excites mercury vapor, which produces short-wave ultraviolet light that then causes a phosphor coating on the inside of the lamp to glow.

Apr 5, 2023 · Fluorescent materials are those that can exhibit this characteristic. At a scientific level, fluorescence can be defined as the absorption of a photon by an atom or molecule, which raises its energy level to an excited state, followed by the emission of a lower-energy photon as the atom or molecule returns to its original state.
The meaning of FLUORESCENT is having or relating to fluorescence. How to use fluorescent in a sentence.
Jun 5, 2024 · fluorescence, emission of electromagnetic radiation, usually visible light, caused by excitation 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.
May 17, 2024 · Fluorescent lamp, electric discharge lamp, cooler and more efficient than incandescent lamps, that produces light by the fluorescence of a phosphor coating. A fluorescent lamp consists of a glass tube filled with a mixture of argon and mercury vapour.
Jan 30, 2023 · Fluorescence, a type of luminescence, occurs in gas, liquid or solid chemical systems. Fluorescence is brought about by absorption of photons in the singlet ground state promoted to a singlet excited ….

Dec 20, 2023 · But the humble fluorescent lamp (aka lightbulb) is still around and as popular as ever, at least in certain situations. If you’re not familiar with fluorescent lighting, the next time you’re in Target or Costco, look up. Unless they’ve updated all their lighting recently, you’re probably looking at fluorescent lamps.
