Abstract
ZnTe single crystals grown by the cold travelling heater method have been investigated by means of photo-and cathodoluminescence. The spectral region covered in this work ranges from 2.48 eV (500 nm) which corresponds to band-edge emission to 0.62 eV (2000 nm). Visible and infrared cathodoluminescence images have been recorded, and the influence of extended defects on the observed luminescence has been studied.
