Dictionary definition of luminous

Detailed meaning of luminous

Luminescent objects or substances have the unique ability to glow or shine in the dark or low-light conditions. Unlike incandescent sources of light, which generate illumination through the release of heat, luminescence occurs when energy is absorbed and then re-emitted as visible light. This term is commonly associated with phenomena such as the gentle glow of phosphorescent paint in the dark or the fluorescence of certain minerals when exposed to ultraviolet light. "Luminescent" conveys a sense of ethereal and otherworldly beauty, often capturing our fascination and wonder with its ability to produce radiant light without the usual heat associated with traditional sources of illumination.
