First-principles calculations based on density functional theory are performed to investigate the structural, electronic and optical properties of monoclinic α-CoV₂O₆. Firstly, the geometry structures obtained by geometry optimization are consistent with the experimental values. Then, the energy band structure is studied using both GGA and GGA+U methods. It is found that the on-site Coulomb repulsion of the Co 3d orbital plays a key role in describing the electronic properties of α-CoV₂O₆, and is necessary to open the energy band gap. According to the partial density of states (PDOS), significant Co-O and V-O hybridizations are observed in the valence and conduction bands, respectively. Furthermore, the Co-O and V-O bonds are found to have significant covalent characters. Below the absorption threshold ~1.9 eV, no absorption can be detected. However, there exists a strong and wide absorption band in the energy range from 1.9 to 11 eV. Such novel optical properties imply that the α-CoV₂O₆ may have some potential optical applications.
