This luminescent effect is achieved with chemicals that can soak up energy, rather like a sponge soaks up water, and then release the energy slowly in the form of visible light. The first example of this was copper-doped zinc sulphide, discovered about 100 years ago. This absorbs energy of various sorts and then allows it to trickle out as visible (green) wavelengths.
