This phenomenon reduces the resolution of detectors doped with cerium three at room temperature, because cerium three creates shallow traps in the phase space at which thermally activated electron-hole recombination occurs. In an organic molecule with pi-structure, intersystem crossing can allow radiation-free electron transfer from an excited singlet state to an excited triplet state, eventually resulting in this. This process is generally undesirable in a scintillation detector, as it places significant restrictions on the maximum count rate and results in "afterglow" due to its long duration. FTP name this form of electronic de-excitation through spontaneous photon emission, a term first used to describe the persistent luminescence of its namesake.
