Emission spectra were measured for separate excitation by light absorbed in the A, B, C, and D impurity absorption bands of single crystals of KI: Tl at 12^∘{}K. Five emission bands are reported. Three emission bands are identified as direct transitions from the energy levels related to the A, B, and C absorption bands. Excitation in the D absorption band is found to excite an additional low-energy emission band which corresponds to a forbidden transition in absorption.
