oxunarefni
Oxunarefni refers to substances that possess the property of luminescence, meaning they emit light. This emission can occur through various mechanisms, and the term is broadly applied to materials that exhibit this phenomenon. One common type of oxunarefni is phosphorescent material, which absorbs energy and then slowly releases it as light over a period of time, often after the initial energy source is removed. Another is fluorescent material, which emits light almost instantaneously when exposed to a specific type of radiation, such as ultraviolet light.
The light emitted by oxunarefni can span the entire electromagnetic spectrum, though visible light emission is
