The decay of cathodoluminescence produced by pulsed excitation has been studied for as-grown and phosphor doped zinc telluride. Analysis of the shift of the peak emission energy positions during the decay has been used to determine acceptor concentrations, transition probabilities, fraction of pairs excited and donor depth. Further substantiative evidence for the assignments by Bryant and Baker (1972) of the four emission bands to transitions into the first and second charge states of a double acceptor centre involving a zinc vacancy has been obtained.
