Luminescence is spontaneous emission of light by a substance not resulting from heat; or "cold light".
Cathodoluminescence is an optical and electromagnetic phenomenon in which electrons impacting on a luminescent material such as a phosphor, cause the emission of photons which may have wavelengths in the visible spectrum. A familiar example is the generation of light by an electron beam scanning the phosphor-coated inner surface of the screen of a television that uses a cathode ray tube. Cathodoluminescence is the inverse of the photoelectric effect, in which electron emission is induced by irradiation with photons.
Bioluminescence is the production and emission of light by a living organism. It is a form of chemiluminescence. Bioluminescence occurs widely in marine vertebrates and invertebrates, as well as in some fungi, microorganisms including some bioluminescent bacteria, and terrestrial arthropods such as fireflies. In some animals, the light is bacteriogenic, produced by symbiotic bacteria such as those from the genus Vibrio; in others, it is autogenic, produced by the animals themselves.
Thermoluminescence dating (TL) is the determination, by means of measuring the accumulated radiation dose, of the time elapsed since material containing crystalline minerals was either heated or exposed to sunlight (sediments). As a crystalline material is heated during measurements, the process of thermoluminescence starts. Thermoluminescence emits a weak light signal that is proportional to the radiation dose absorbed by the material. It is a type of luminescence dating.
Monthly Notices of the Royal Astronomical Society (MNRAS) is a peer-reviewed scientific journal covering research in astronomy and astrophysics. It has been in continuous existence since 1827 and publishes letters and papers reporting original research in relevant fields. Despite the name, the journal is no longer monthly, nor does it carry the notices of the Royal Astronomical Society.
Google Scholar is a freely accessible web search engine that indexes the full text or metadata of scholarly literature across an array of publishing formats and disciplines. Released in beta in November 2004, the Google Scholar index includes most peer-reviewed online academic journals and books, conference papers, theses and dissertations, preprints, abstracts, technical reports, and other scholarly literature, including court opinions and patents. Google Scholar uses a web crawler, or web robot, to identify files for inclusion in the search results. For content to be indexed in Google Scholar, it must meet certain specified criteria. An earlier statistical estimate published in PLOS One using a Mark and recapture method estimated approximately 80–90% coverage of all articles published in English with an estimate of 100 million. This estimate also determined how many documents were freely available on the internet.
Absolute dating is the process of determining an age on a specified chronology in archaeology and geology. Some scientists prefer the terms chronometric or calendar dating, as use of the word "absolute" implies an unwarranted certainty of accuracy. Absolute dating provides a numerical age or range, in contrast with relative dating, which places events in order without any measure of the age between events.
Luminescence dating refers to a group of methods of determining how long ago mineral grains were last exposed to sunlight or sufficient heating. It is useful to geologists and archaeologists who want to know when such an event occurred. It uses various methods to stimulate and measure luminescence.

According to the Journal Citation Reports, the journal has a 2020 impact factor of 3.599, ranking it 24th out of 99 in the category Optics. The journal covers all aspects related to the emission of light (luminescence).
Jaak Aaviksoo is an Estonian politician and physicist, a former rector of the University of Tartu and Tallinn University of Technology (TalTech).
Luminescence: The Journal of Biological and Chemical Luminescence is a bimonthly peer-reviewed scientific journal publishing original scientific papers, short communications, technical notes, and reviews on fundamental and applied aspects of all forms of luminescence, including bioluminescence, chemiluminescence, electrochemiluminescence, sonoluminescence, triboluminescence, fluorescence, time-resolved fluorescence, and phosphorescence. The current editor-in-chief is L.J. Kricka. It was established in 1986 by John Wiley & Sons as the Journal of Bioluminescence and Chemiluminescence and obtained its current title in 1999.
The Electrochemical Society is a learned society based in the United States that supports scientific inquiry in the field of electrochemistry and solid-state science and related technology. The Society membership comprises more than 8,000 scientists and engineers in over 85 countries at all degree levels and in all fields of electrochemistry, solid state science and related technologies. Additional support is provided by institutional members including corporations and laboratories.
A law review is a scholarly journal or publication that focuses on a wide array of legal issues. A law review is a type of legal periodical. Typically, the law students initiate the production of the journals, with the publication of articles that are authored by law faculty and law scholars. The law students add references, notes and comments in the topics contained in the reviews.
The United States Stamp Society (USSS) is the largest philatelic organization dedicated to the research and study of United States postage and revenue stamps. The Society is a non-profit collector-based organization with a world-wide membership of over 1700. The USSS is Affiliate #150 of the American Philatelic Society (APS). Since 1930 the Society has encouraged philatelic study through voluntary membership in specialized committees. Some committees specialize in specific stamp issues like the Washington-Franklin heads, the Prexie or the Liberty Series, while other committees study specialized areas of U.S. philately such as Plate Numbers and Marginal Markings, Private Vending and Affixing Perforations, Booklets and Panes, and Luminescence. Research is made available through published books, research papers and articles in the monthly journal, The United States Specialist.
The Journal of Contemporary History is a quarterly peer-reviewed academic journal covering the study of history in all parts of the world since 1930. It was established in 1966 by Walter Laqueur and George L. Mosse. Originally published by Weidenfeld & Nicolson it was purchased by Sage Publications in 1972. The editors-in-chief are Richard J. Evans and Mary C. Neuberger.
Ioannis Liritzis is professor of physics in archaeology (archaeometry) and his field of specialization is the application of natural sciences to archaeology and cultural heritage. He studied physics at the University of Patras and continued at the University of Edinburgh, where he obtained his Ph.D. in 1980. Since then, he undertook postgraduate work at the University of Oxford, Université Bordeaux III, University of Edinburgh and the Academy of Athens.
Luminescence is emission of light by a substance not resulting from heat.
Judd–Ofelt theory is a theory in physical chemistry describing the intensity of electron transitions within the 4f shell of rare-earth ions in solids and solutions.
Chronological dating, or simply dating, is the process of attributing to an object or event a date in the past, allowing such object or event to be located in a previously established chronology. This usually requires what is commonly known as a "dating method". Several dating methods exist, depending on different criteria and techniques, and some very well known examples of disciplines using such techniques are, for example, history, archaeology, geology, paleontology, astronomy and even forensic science, since in the latter it is sometimes necessary to investigate the moment in the past during which the death of a cadaver occurred. These methods are typically identified as absolute, which involves a specified date or date range, or relative, which refers to dating which places artifacts or events on a timeline relative to other events and/or artifacts. Other markers can help place an artifact or event in a chronology, such as nearby writings and stratigraphic markers.
