In a spinel! Spinel zinc gallium oxonitrides (Eg<3 eV, see figure) synthesized by nitridation of a zinc gallate precursor show improved activity for the oxidation of organic molecules in visible light. DFT calculations show that the bandgap reduction is in part associated with hybridization between the dopant N 2p states and Zn 3d orbitals at the top of the valence band.
