When glow in the dark paint is exposed to black light, it will also absorb the UV radiation and then re-emit it as visible light. Glow in the dark paint is a phosphorescent paint that contains a rare earth element called strontium aluminate. When this substance is exposed to light, it stores the energy and re-emits it as visible light in the dark.

What are the processes that occur during glow in the dark?
While most glow-in-the-dark materials rely on phosphorescence because the glow lasts a long time (hours or even days), other luminescent processes occur. In addition to fluorescence, thermoluminescence, and triboluminescence, there are also radioluminescence (radiation besides light is absorbed and released as photons), crystalloluminescence (light is released during crystallization), and sonoluminescence (absorption of sound waves lead to light release).
