Abstract

The electronic structure of normal spinel structure ZnRh ₂O ₄ is investigated using combined optical properties measurements and density functional calculations. We find semiconducting behavior with an indirect band gap between crystal field split Rh 4d levels, with a t _2g valence band and an e _g conduction band. The band gap is found to be ∼1.2 eV based on a comparison of the calculated and measured optical conductivities. The results are discussed in terms of potential photoelectrochemical applications.
