The luminescence decay times of Tl + ‐type ions in MgS, CaS, SrS, and BaS are measured as a function of temperature from 4.2 to 150 K. By applying a three‐level model, the energy difference Δ E between the lower excited states 3 T 1u ( 3 P 1 ) and 3 A 1u ( 3 P 0 ) and the transition probabilities from the two excited states to the ground state 3 A 1g ( 1 S 0 ) are derived. The values of the parameters are compared with each other and with those for alkaline‐earth oxides.
