Image Luminol.jpg right thumb Luminol and hemoglobin , an example of chemoluminescence commonscat Luminescence is light that usually occurs at low temperatures, and is thus a form of cold body radiation . It can be caused by chemical reaction s, electrical energy , subatomic motion s, or Stress physics stress on a crystal . This distinguishes luminescence from incandescence , which is light generated by high temperatures. Historically, radioactivity was thought of as a form of radioluminescence , although it is today considered to be separate since it involves more than electromagnetic radiation. The dials, hands, scales and signs of aviation and navigational instruments and markings are often coated with luminescent materials, in a process known as luminising. The following are types of luminescence Bioluminescence , by a living organism Chemoluminescence , resulting of a chemical reaction Electrochemiluminescence , by an electrochemical reaction Crystalloluminescence , produced during crystallization Electroluminescence , in response to an electric current passed through it Cathodoluminescence , where beam of electrons impacts on a luminescent material such as a phosphor Mechanoluminescence , resulting from any mechanical action on a solid Triboluminescence , generated when bonds in a material are broken when that material is scratched, crushed, or rubbed Triboluminescence Fractoluminescence Fractoluminescence , generated when bonds in certain crystals are broken by fractures Piezoluminescence , produced by the action of pressure on certain solids ref http adsabs.harvard.edu ...

Negative luminescence is a physical phenomenon by which an electronic device emits less thermal radiation when an electric current is passed through it than it does in thermal equilibrium current off . When viewed by a thermal camera , an operating negative luminescent device looks colder than its environment. Physics Negative luminescence is most readily observed in semiconductor s. Incoming infrared radiation is absorbed in the material by the creation of an electron hole pair . An electric field is used to remove the electrons and holes from the region before they have a chance to recombine and re emit thermal radiation. This effect occurs most efficiently in regions of low charge carrier density. Negative luminescence has also been observed in semiconductors in orthogonal electric and magnetic fields. In this case, the junction of a diode is not necessary and the effect can be observed in bulk material. A term that has been applied to this type of negative luminescence is galvanomagnetic luminescence . Negative luminescence might appear to be a violation of Kirchhoff s law of thermal ...

Orphan date February 2009 Commonly referred as phosphorescence, persistent luminescence is the phenomenon encountered in materials which make them glow in the dark after the end of an Excited state excitation with UV or visible light. Mechanism The mechanism underlying this phenomenon is not fully understood ref T. Aitasalo, P. Deren, J. H ls , H. Jungner, J.C. Krupa, M. Lastusaari, J. Legendziewicz, J. Niittykoski, and W. Strek. Persistent luminescence phenomena in materials doped with rare earth ions. J. Solid State Chem. , 171 114, 2003 . ref . However, the phenomenon of persistent luminescence must not be mistaken with fluorescence and phosphorescence see for definitions ref http goldbook.iupac.org F02453.html IUPAC Gold Book fluorescence Bot generated title ref and ref http goldbook.iupac.org P04569.html IUPAC Gold Book phosphorescence Bot generated title ref . Indeed, in fluorescence, the lifetime of the excited state is in the order of a few nanoseconds and in phosphorescence, even if the lifetime of the emission can reach several seconds, the reason of the long emission is due to the deexcitation between two electronic states of different spin multiplicity . For persistent luminescence, it has been known for a long time that the phenomenon involved energy traps such as electron or hole trap in a material ref H.W. Leverenz. Luminescent solids phosphors . Science , 109 183 189, 1949 . ref which are filled during the excitation. After the end of the excitation, the stored energy is gradually released to emitter centers which emit light usually by a fluorescence like mechanism. Examples of use Persistent luminescence materials are mainly used in safety signs, watch dials, decorative objects and toys.

Photostimulated luminescence PSL is the release of stored energy within a phosphor by stimulation with visible light, to produce a luminescent signal. Commonly this is used to allow the storage of a weak radioactive signal in a phosphor plate that takes the place of X ray film, potentially over a prolonged period, which PSL transforms to obtain a highly sensitive image of the original pattern of radiation. Also known as an image plate , a photostimulable phosphor PSP plate can be used record a two dimensional image of the intensity short electromagnetic spectrum wavelength typically, X ray electromagnetic radiation . The device to read such a plate is known as a phosphorimager occasionally abbreviated to phosphoimager , perhaps reflecting its common application in molecular biology of detecting radiolabel ed phosphorylated proteins and nucleic acids . Creating an image requires illuminating the Photographic plate plate twice the first exposure, to the radiation of interest, writes the image, and a later, second illumination typically by a visible wavelength laser reads the image. Basic Explanation After the initial exposure, excited electrons in the phosphor material remain trapped in colour centres in the crystal crystal structure lattice until stimulated by the second illumination. For example, Fuji s photostimulable phosphor is deposited on a flexible polyester film support with grain size about 5 micrometers , and is described as barium fluorobromide containing a trace amount of bivalent europium as a luminescence center . Europium is a divalent cation that replaces barium to create a solid solution . When Eu sup 2 sup ions are struck by ionizing radiation, they lose an additional electron to become Eu sup 3 sup ions. These electrons enter the conduction band of the crystal .... As these mobilized electrons encounter Eu sup 3 sup ions, they release a blue violet 400 nm luminescence ... image . This process is also known as Photostimulable Luminescence PSL . Unlike film , a PSP plate can ... more details

mergeto Optical dating discuss Talk Optical dating Merger proposal date January 2011 In physics , optically stimulated luminescence OSL is a method for measuring doses from ionizing radiation . The method makes use of electron s trapped between the valence and conduction bands in the Crystal crystalline structure of certain types of matter such as quartz , feldspar , and aluminum oxide . The trapping sites are imperfections of the lattice impurities or crystallographic defect defects . The ionizing radiation produces electron hole pairs electrons are in the conduction band and holes in the valence band . The electrons which have been excited to the conduction band may become entrapped in the electron or hole traps. Under stimulation of light the electrons may free themselves from the trap and get into the conduction band. From the conduction band they may recombine with holes trapped in hole traps. If the centre with the hole is a luminescence centre radiative recombination centre emission of light will occur. The photon s are detected using a photomultiplier tube. The signal from the tube is then used to calculate the dose that the material had absorbed. OSL is used in at least two different applications optical dating of ancient materials mainly geological sediments, but also sometimes fired pottery, bricks etc., although in the latter case thermoluminescence dating is used more often radiation dosimetry , which is the measurement of accumulated radiation dose in the tissues of health care, nuclear, research and other workers, as well as in building materials in regions of nuclear disaster In order to carry out OSL dating, mineral grains have to be extracted from the sample. Most commonly these are so called coarse grains 100 200 m, or fine grains 4 11 m. Occasionally other grain sizes are used. The difference between radiocarbon dating and OSL is that the former is used to date organic materials, while the latter is used to date minerals. Events that can be dat ... more details
