A secondary cation insertion technique to fabricate ternary Bi₂MoO₆ thin films with reduced optical band gaps and shallow valence bands by the controllable insertion of Bi³⁺ cations into anodized MoO₃ thin films has been established. Near-complete conversion of the MoO₃ thin film to a low-temperatur...
