Fluorescence is a phenomenon in which a substance emits light when it is exposed to electromagnetic radiation. Synonyms for the word "fluorescing" include glowing, radiating, shining, and luminescing. These terms are often used interchangeably to describe the emission of light from a substance. However, each term may carry a slightly different connotation. For example, "glowing" may imply a softer, warmer light, while "radiating" may suggest a more intense, directional emission. In scientific contexts, "fluorescing" is often used to describe the specific process of energy absorption and emission that produces fluorescence. Regardless of the terminology used, fluorescence is a fascinating and useful property of many materials.
