ZnO nanostructures have been prepared via the evaporation of zinc under different atmospheres (see Figure). No relationship has been shown to exist between the g = 1.96 electron paramagnetic resonance (EPR) spectroscopy signal and green photoluminescence; this contradicts the commonly assumed transition which occurs between a singly charged oxygen vacancy and a photoexcited hole.
