Tuning the band gap and structure from wide gap SrBi <sub>3</sub> O <sub>4</sub> Cl <sub>3</sub> to narrow gap Bi <sub>4</sub> O <sub>4</sub> SeCl <sub>2</sub> by aliovalent anion substitution
Aliovalent substitution can generates a complex solid solution between SrBi 3 O 4 Cl 3 and Bi 4 O 4 SeCl 2 with very different band gaps, leading to a nearly isolated Se p band and two distinct band-gap like onset energies in intermediate compounds.
