luminescence - light not due to incandescence; occurs at low temperatures. light, visible light, visible radiation - (physics) electromagnetic radiation that can produce a visual sensation; the light was filtered through a soft glass window.
Molecules in the substances absorb the invisible ultraviolet light and are energized, then shed their excess energy by emitting visible light. See Luminescence. As another example, ordinary window glass, transparent to visible light, is opaque to a large range of ultraviolet rays, particularly those with short wavelengths.
