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.
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.
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 ….
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.
The meaning of FLUORESCENT is having or relating to fluorescence. How to use fluorescent in a sentence.
Fluorescence is the result of a three-stage process that occurs in certain molecules (generally polyaromatic hydrocarbons or heterocycles) called fluorophores or fluorescent dyes ( Figure 1 ). A fluorescent probe is a fluorophore designed to respond to a specific stimulus or to localize within a specific region of a biological specimen.
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.
FLUORESCENT meaning: 1 : producing light when electricity flows through a tube that is filled with a type of gas; 2 : very bright
Fluorescence is the property of some atoms and molecules to absorb light at a particular wavelength. A microplate reader with fluorescence intensity (FI) detection uses a light to excite a fluorescent molecule.
FLUORESCENT definition: 1. producing light by fluorescence (= absorbing light of a short wavelength and producing light of…. Learn more.
