The 3000 Å emission of KCl:Tl + which contains a fast and a slow decay process was investigated by time‐resolved emission spectroscopy. This technique permits sampling of photons which are emitted at a chosen delay time after excitation. Emission and excitation spectra and the polarization of emission were measured separately for both components with and without applied stress. The results give information about the Jahn‐Teller effect of the 3 T 1u , and 3 A 1u excited states. It is concluded that the 3 A 1u ‐APES follows the 3 A 1u ‐APES near the potential minima.
