luminescence Dictionary Terms

Stokes line
A line of the Raman spectrum that fulfills Stokes' law because it possesses a wavelength that is greater than the radiation...
fiber-based confocal luminescence microscope
A microscope in which laser light is delivered through single-mode fibers that replace the pinhole usually used in confocal...
fluorescence
Fluorescence is a type of luminescence, which is the emission of light by a substance that has absorbed light or other...
thermoluminescence
An alternative term for incandescence.
chemiluminescence
A chemical reaction involving the production of light. The reaction of ethylene with ozone is chemiluminescent.
fiber-coupled LED
A fiber-coupled LED (light-emitting diode) refers to an LED device that is optically coupled to an optical fiber for the...
haze factor
The ratio between the luminescence of an object and the luminescence of the scattering medium through which it is being...
light-emitting diode
An LED, or light emitting diode, is a semiconductor device that emits light when an electric current passes through it. LEDs...
cathodoluminescence
Light produced when a metal is bombarded with high-velocity electrons causing small amounts of the metal to vaporize and...
luminescent greenhouse collector
A collector for photovoltaic power generation that consists of a thin plate that strongly absorbs sunlight striking its...
airglow
Diffuse light emitted by the atmosphere due to the excitation of particles of atmospheric gas. These excited particles...
active-matrix OLED display
An OLED display that has an integrated electronic backplane as its substrate. Active-matrix OLED displays use at least two...
field emission display
An X-Y electrically addressable series of arrays with individual electron emitters bombarding a phosphor-coated transparent...
bioluminescence
Heatless light emissions from living organisms caused by the combination of oxygen and pigments such as luciferin.
intensified charge-coupled device camera
An intensified charge-coupled device (ICCD) camera is an advanced imaging device that combines the capabilities of both an...
fluorescence photography
The photographic recording of a subject that exhibits luminescence only for an extremely short time (10-8 s) after the...
radiophotoluminescence
The luminescence displayed when particular minerals are irradiated with β-rays and g-rays, after being exposed to...
infrared phosphor
A phosphor, such as sulfide or selenide, that can be excited to luminescence by incident infrared radiation simultaneous to...
impurity level
In the context of optical materials, the term "impurity level" refers to the presence of foreign atoms or molecules within...
autoluminescence
The luminescence of a substance that is produced by energy within it (e.g., radioactive material).
luminescence
Luminescence is the emission of light that occurs without the involved substance undergoing a significant increase in...
triboluminescence
Luminescence that arises from friction and that usually occurs in crystalline materials.
electroluminescence
The nonthermal conversion of electrical energy into light in a liquid or solid substance. The photon emission resulting from...
phosphorescence
Luminescence is the emission of light from a source that is delayed by more than 10-8 s following excitation.
galvanoluminescence
The emission of radiant energy produced by the passage of an electrical current through an appropriate electrolyte in which...
sonoluminescence
The luminescence of a substance resulting from its exposure to ultrasonic waves.
Destriau effect
Observed electroluminescence of zinc sulfide phosphors when excited by an electric field. This effect is the basis for the...
tunnel luminescence
Light that is emitted from a phosphor film applied to the surface of a three-layer thin film, respectively metal, oxide and...
candoluminescence
The luminescence of an incandescent material.
PN-junction luminescence
Discharge that results when a doped semiconductor crystal with a PN junction is charged with a low-voltage direct current....
electronoluminescence
 Stokes' law
Relative to radiation wavelength, the law that states that the wavelength of luminescence stimulated by radiation always...
band-to-band photoluminescence
The emission of a photon by the return of an excited carrier from the conduction band to the valence band of a semiconductor...
photoluminescence mapping
A technique used for noncontact inspection of semiconductor wafers. The material is illuminated by an excitation source that...
radioluminescence
Luminescence produced by the bombardment of radiant energy such as x-rays, radioactive waves or alpha particles.
