There are two types of luminescence: fluorescence and phosphorescence. Fluorescence is the process of absorbing and re-emitting light on a timescale of about 10-8 seconds while phosphorescence processes are much slower, taking about 10-3 to 1 second to occur (even longer lifetimes are possible).

The two phenomena of fluorescence and phosphorescence are not as common as simple reflection and transmission, but do have an important part to play in the complete description of macroscopic physical behavior that should be modeled by image synthesis programs.
