Crystalloluminescence is the effect of luminescence produced during crystallization . The abstract of an article by B. P. Chandra, V. Kalia and S. C. Datt of Rani Durgavati University Jabulpur, India , entitled Crystalloluminescence a new tool to determine the critical size of a crystal nucleus , states There is a time lag between the achievement of supersaturation in a solution and the appearance of crystalloluminescence flashes from crystal nuclei. The incubation time of crystalloluminescence decreases systematically with the concentration of the solution. A new method based on crystalloluminescence measurements is proposed for the determination of the critical size of the crystal nucleus.

Image Luminol.jpg right thumb Luminol and haemoglobin , an example of chemiluminescence commons category Luminescence is emission of light by a substance not resulting from heat it is thus a form of cold body radiation . It can be caused by chemical reaction s, electrical energy , subatomic motions, or Stress physics stress on a crystal . This distinguishes luminescence from incandescence , which is light emitted by a substance as a result of heating. Historically, radioactivity was thought of as a form of radio luminescence , although it is today considered to be separate since it involves more than electromagnetic radiation. The term luminescence was introduced in 1888 by Eilhard Wiedemann . ref A Brief History of Fluorescence and Phosphorescence before the Emergence of Quantum Theory Bernard Valeur and Mrio N. Berberan Santos J. Chem. Educ., 2011, 88 6 , pp 731 738 DOI 10.1021 ed100182h ref 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 , emission by a living organism Chemiluminescence , a result of a chemical reaction Electrochemiluminescence , a result of an electrochemical reaction Crystalloluminescence , produced during crystallization Electroluminescence , a result of an electric current passed through a substance Cathodoluminescence , a result of being struck by an electron Mechanoluminescence , a result of a 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 Piezoluminescence phenomenon N.
