The emission processes in the TSEE and TL glow peaks of KCl:Ag single crystals are discussed from the results of simultaneous recording of TSEE and TL glow curves, the spectral measurements of the TL and the optical re‐excitation study. A large fraction of the exoelectron emissions at 400 K may be considered to arise from Auger‐like decays of the excited Ag + centers induced by the recombination of electrons from Ag 0 with Ag 2+ via the conduction band. The 275 nm emission band of TL at 400 K may be due to competing radiative decays of the excited Ag + centers. The electron emissions and the 275 nm component of TL at 250 K may originate from the excited Ag + centers resulting from the recombination of F′ (or F) centers with Ag + centers.
