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.
FLUORESCENT definition: 1. producing light by fluorescence (= absorbing light of a short wavelength and producing light of…. Learn more.
The meaning of FLUORESCENT is having or relating to fluorescence. How to use fluorescent in a sentence.
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.
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.
In this article, we'll find out how fluorescent lamps emit such a bright glow without getting scalding hot like an ordinary light bulb. We'll also find out why fluorescent lamps are more efficient than incandescent lighting, and see how this technology is used in other sorts of lamps.
Jun 13, 2011 · The basic theory behind the phenomenon of photoluminescence – fluorescence and phosphorescence. Fluorescence was first described by George Gabriel Stokes in 1852 [1]. He observed that fluorite glows after being illuminated with ultraviolet light. Fluorescence is a form of photoluminescence, i.e., the emission of photons after a material is ...
Jun 27, 2019 · Fluorescent objects reflect light as well as absorb the energy of the light, turning some of it into heat, and the majority of the light is emitted as the fluorescent colour. The electrons in the fluorescent pigments absorb light energy and are temporarily promoted into higher-energy orbitals.
Mar 20, 2017 · Fluorescence is the ability of certain chemicals to give off visible light after absorbing radiation which is not normally visible, such as ultraviolet light. This property has led to a variety of uses.
