AbstractThe 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 ΔE between the lower excited states 3T1u(3P1) and 3A1u(3P0) and the transition probabilities from the two excited states to the ground state 3A1g(1S0) are derived. The values of the parameters are compared with each other and with those for alkaline‐earth oxides.
