Luminescence is a phenomenon where a substance emits light without a significant rise in temperature. Luminescence can be broadly categorized based on the energy source that triggers the light emission. Photoluminescence occurs when a substance absorbs photons (light energy) and then re-emits photons. This category includes fluorescence, where the emission is rapid, and phosphorescence, where the emission is delayed. Chemiluminescence is triggered by a chemical reaction, producing light as a byproduct. Bioluminescence is a specific type of chemiluminescence that occurs in living organisms, such as fireflies or certain deep-sea creatures. Triboluminescence is generated by mechanical action, such as friction or fracturing of a material. Electroluminescence is the emission of light by a substance in response to an electric current or field. Thermoluminescence is the emission of light from a substance that has been previously exposed to radiation, and then heated. Crystalloluminescence is light produced during crystallization. Mechanoluminescence encompasses light emission from deformation or breakage of solids. Each type of luminescence has distinct mechanisms and applications, ranging from scientific research and medical diagnostics to industrial processes and artistic displays.
