Effect of increased pressure (up to 1.5GPa) during annealing of Cz-Si on creation of thermal donors (at 720 - 1000K) and visible luminescence (peaking at 1.7- 2.2eV for samples annealed at up to 1420K) is reported. The observed phenomena are related to stress - stimulated oxygen clustering / precipitation in Cz-Si resulting in creation of specific defects.
