Tunable band gaps of Co3−xCuxO4 nanorods with various Cu doping concentrations

Author affiliations

Abstract

Co3−xCuxO4 nanorods with a crystalline structure were synthesized via a solution process in this study. The Co3−xCuxO4 nanorods exhibit dual direct bandgaps and could be adjusted to 1.3–1.5 eV, and 2.55–3.5 eV by using different Cu-doping concentrations. The Co3−xCuxO4 nanorods show an absorption coefficient of ∼104 cm−1 which increases with the increase of the Cu doping concentration.
