Abstract

Oxygen is found to diffuse from an oxygen-rich atmosphere into ZnTe during micro- and millisecond laser annealing. The typical red oxygen band is observed in the photoluminescence spectra after annealing. The intensity of this band depends on the oxygen partial pressure in the atmosphere, and on the length of the laser pulses. In the high-energy part of the luminescence spectrum, an intense line at an energy of 2.360 eV is found.
