Photoluminescence and its temperature dependence of unintentionally doped zinc telluride crystals grown by sublimation method have been studied. Photoluminescence spectrum at room temperature
which is excited by the 4880Å line of'Ar
+
-ion laser
contains only one band centered at 18190cm
-1
and at liquid nitrogen temperature consists of four bands peaking at 19054cm
-1
18739cm
-1
18528cm
-1
and 18314cm
-1
respectively.According to the energy and intensity dependence
the bands of 18528cm
-1
and 18314cm
-1
in PL spectrum observed at 77K are identified as the one LO and two LO phonon associated
respectively
replicas of the band of 18739cm
-1
.The temperature dependence of the photoluminescence spectrum shows that the band of 18739cm
