(color online) Electron paramagnetic resonance(EPR) spectra of electron-irradiated ZnO at 30 K and 9.48 GHz, with the magnetic field perpendicular to the c axis, respectively (a) in the dark and (b) after illumination with 325-nm light. The Zn vacancies are in the 1–charge state, and the O vacancies are in the 2+ charge state.[32] The unit 1 Gs = 10 T.
