fluorescence
Absorbed light released
Fluorescence is the emission of light by a substance that has absorbed radiation, where the emitted light typically has a longer wavelength than the absorbed light.
The effect is immediate and stops when the light source is removed, distinguishing it from phosphorescence, which continues to glow.
Many materials fluoresce under ultraviolet light, producing vivid colors invisible under normal lighting.
The fluorescence of the minerals was spectacular under the black light.
