- •
La-doping showed a red shift of absorption, reaching the visible region.
- •
La-doping increased the coordination number of oxygen surrounding the Bi3+-site.
- •
The energy band calculations showed the band gap narrowing by La-doping.
- •
A superior photocatalytic performance was observed under visible-light.
