Theoretical insight into the electronic, optical and photocatalytic properties of InMO4 (M = V, Nb, Ta) photocatalysts

The electronic and optical properties of InMO4 (M = V, Nb, Ta) photocatalysts are studied using first-principles calculations. For all InMO4, the calculated band gaps are larger than the measured optical gaps, indicating the existence of sub-bandgap transitions. Impurity states and excitons are cons... Full description
