Where this comes from

Abstract

GaP-ZnS solid solutions and multilayered structures have a tunable direct band gap in the energy range for absorption and emission of visible light. A direct band gap of around 2.0 eV, the optimum for photocatalysis of water splitting, is readily accessible with these systems.
