Oxygen vacancies often determine the electronic structure of metal oxides, but existing techniques cannot distinguish the oxygen-vacancy sites in the crystal structure. We report here that time-resolved optical spectroscopy can solve this challenge and determine the spatial locations of oxygen vacancies. Using tungsten oxides as examples, we identified the true oxygen-vacancy sites in WO<sub>2.9</sub> and WO<sub>2.72</sub>, typical derivatives of WO<sub>3</sub> and determined their fingerprint o ...[more]
