| Abstract: | High energy electron irradiation of ZnTe crystals at 4 K gives rise to a new luminescence line at 2.361 eV and to a broad band at 1.578 eV. These features disappear on annealing at T? 180 K. The defect responsible for these radiative transitions is tentatively identified with Frenkel type close pair. Another broad line at 2.065 eV appears after a 77 irradiation. Its annealing temperature is near 300 K. |
