Depens on the molecules of the thing.

Usually you shine radiation over something, and what happens is that the molecules of that thing will first absorb the energy (unlesd the thing is transparent to that radiation) and inmediately will re-emit it. The re-emision can be the same (a mirror reflects your image) or maybe part of the energy remains on the material (as heat) so the re emission is shifted. Those materials that you ask just absorb the radiation, take part of the enery as heat, and the rest they emit it again..as glowing light.
