Oxygen vacancies and their kinetic behaviours were systematically investigated in quenched BiFeO3 ceramics. Complex relaxation processes were observed and discussed based on the migration of Vo+ ?>, Vo2+ ?> and the transition in between them, where Vo+ ?>, Vo2+ ?> represent the oxygen vacancies with single and two positive charges, respectively. It is found that an oxygen-deficient environment promotes the transformation from Vo+ ?> to Vo2+ ?>, while oxygen treatment can reverse such a transformation. This work provides a feasible alternative method to modulate oxygen vacancies and their migration in favour of the applications of BiFeO3.
