fluorescence
The light so emitted
The ability of a substance, such as paper or ink, to absorb ultraviolet light waves and reflect them as visible light
It is due not to the difference in the color of a distinct surface layer, but to the power which the substance has of modifying the light incident upon it
{i} emission of electromagnetic radiation (especially as visible light); fluorescent light
The light emitted by fluorescent substances is in general of lower refrangibility than the incident light
The glow induced in a material when bombarded by light Brewster windows of fused silica fluoresce in UV light, increasing absorption of laser radiation and degrading laser mode and output
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. Because re-emission occurs so quickly, the fluorescence ceases as soon as the exciting source is removed, unlike phosphorescence, which persists as an afterglow. A fluorescent lightbulb is coated on the inside with a powder and contains a gas; electricity causes the gas to emit ultraviolet radiation, which then stimulates the tube coating to emit light. The pixels of a television or computer screen fluoresce when electrons from an electron gun strike them. Fluorescence is often used to analyze molecules, and the addition of a fluorescing agent with emissions in the blue region of the spectrum to detergents causes fabrics to appear whiter in sunlight. X-ray fluorescence is used to analyze minerals
Emission of visible light by a substance, such as a mineral, that is currently exposed to ultraviolet light and absorbs radiation from it The light appears in the form of glowing, distinctive colors The emission ends when the exposure to ultraviolet light ends
The emission of light (or other electromagnetic radiation) by a material when stimulated by the absorption of radiation or of a subatomic particle
Fluorescence is the property of certain molecules, or fluorophores, to absorb light at one wavelength and emit a light at a longer wavelength The incident light excites the molecule to a higher level of vibrational energy As the molecule returns to the ground state, the excited fluorophore emits a photon This photon is the fluorescence emission If the molecule returns to the ground state through an intermediate excited triple state, there is a delay in the emission of the photon This delayed photon is termed a phosphorescence emission
Absorption of high energy radiation by a substance and subsequent emission of visible light
The re-emission of light energy at a lower frequency by an absorber illuminated with optical energy The response is usually immediate and on order 1 to 3% of the incident intensity
Electrons absorb energetic radiation (for example ultraviolet light) raising an electron to a higher "Bohr" orbit The energized electron soon drops down in a series of steps through lower energy states and in the process releases photons at lower energy states corresponding to visible light The bright color occurs because the photons are concentrated in a narrow range of wavelengths
The property of a material to emit light when it is exposed to different wavelengths of light or X-rays The presence of fluorescence and its strength may greatly affect the quality of a gemstone
A physical process at which the materials pigments absorb light and re-radiate this light as a different color, giving the color of the material extra light or brilliance
The property possessed by some minerals to emit a glow or light during exposure to ultraviolet light
Emission of secondary light generated by excitation by ultraviolet light, a beta particle or a gamma ray
The emission of electromagnetic radiation following absorption of shorter wave length light
