An atom must be in an excited state in order to emit a photon. When an atom absorbs energy, its electrons become excited and move to higher energy levels. As the electrons return to their lower energy levels, they release energy in the form of a photon. This is how light is produced in many different contexts, including in stars and in fluorescent bulbs.
