Decay Times (tau) of the emission of oxygen bound excitons in ZnTe:O w
ere measured from 5 to 300 K. The temperature dependence of tau is det
ermined by the laser excitation energy: for resonant excitation into t
he oxygen vibrational band, a new and different behaviour appears with
respect to the band to band excitation. Interactions which are respon
sible for the temperature dependence of tau at different excitation en
ergies are discussed.
