The phosphor photoluminesces when exposed to ultraviolet light.

The photoluminescent paint glowed in the dark.

Photoluminescence is the emission of light from a material after the absorption of photons.

The phosphor material used in the LED bulb can photoluminesce when excited by the electric current.

The phosphor photoluminesced when exposed to ultraviolet light.

The phosphor is photoluminescing under UV light.

Photoluminescences are commonly used in fluorescence microscopy.
