Description
The voids in α-Al2O3 irradiated by 85 MeV 19F ions of 5.28 x 1016 cm-2 have been observed during the post-annealing by a positron annihilation lifetime technique for the first time. The voids start to appear at 450 degree C. The void radius keeps nearly constant at ∼0.29 nm and the number of voids increases with increasing the annealing temperature from 550 degree C to 750 degree C. Afterwards, the radius of voids increases rapidly with the annealing temperature and reaches 1.10 nm at 1050 degree C
