Accurate Determination of the Bandgap Energy of the Rare-Earth Niobate Series

[Image: see text] We report diffuse reflectivity measurements in InNbO(4), ScNbO(4), YNbO(4), and eight rare-earth niobates. A comparison with established values of the bandgap of InNbO(4) and ScNbO(4) shows that Tauc plot analysis gives erroneous estimates of the bandgap energy. Conversely, accurat...
