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.
