Paper Abstract

Optical absorption bands in two complex oxides are characterised using ab initio simulations and an embedded cluster method. In sub-nanoporous 12CaO.7Al2O3 the width of the optical gap can be controlled by modifying the chemical identities and relative concentration of extra-framework species. In antiferromagnetic LaCrO3, Cr 3d states split into four narrow one-electron bands and give rise to several types of the optical transitions. Their excitation energies respond differently to lattice strain, thus, providing a possibility for tuning the excitation energies in supported LaCrO3 films by selecting appropriate substrates.
