A white body reflects all electromagnetic radiation and a black body absorbs all electromagnetic radiation (interior of that element of the ordinary spectrum of activity). ordinary photons artwork jointly with the electrons orbiting atoms and molecules and are released as similar or diverse photons. Black bodies emit in reality infrared (lower than red on the spectrum) which we journey as warm temperature truly than seen ordinary.

Phosphorescent, if the light continues to be emitted for a while after the exciting source (usually UV) is turned off.
Fluorescent if the the light ceases to be emitted the instant the exciting source is turned off.

is he talking about thermoluminescence? coz thats what it seems like ... if its thermoluminescence then its a photon that is released if a chemical that naturally emits lights its a phosphur. But when u radiate something in thermoluminescences u increase the electron energy levels thus they drop from traps and emit a photon.
