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 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 abs 1982PhLA...90...93A ref Photoluminescence , absorption of photons causing re radiation of photons Phosphorescence , delayed re radiation Fluorescence , where the emitted photons are of lower energy than those absorbed Radioluminescence , produced in a material by the bombardment of ionizing radiation Sonoluminescence , from imploding bubbles in a liquid when excited by sound Thermoluminesc ... more details
