What you see glowing under a black light, whether on a fluorescent poster or an
invisible hand stamp or a newly washed white T-shirt, are phosphors.
A phosphor is any substance that emits visible light in response to some sort of
radiation.
A phosphor converts the energy in the UV radiation from a black light into
visible light.
