Fluorescence occurs when a photon is absorbed by a fluorophore, raising an electron to an excited energy state, from which it relaxes to the electronic ground state and emits a lower energy photon. For absorption to occur, the energy of the exciting photon has to approximately match the energy difference between the excited state and
