The magnetic, electronic and optical properties of Co2-xEuxVSn alloys for selected concentrations (x = 0, 0.25, 0.50, 0.75 and 1.0) were investigated by means of density functional theory (DFT) calculations utilizing full potential linearized augmented plane wave (FP-LAPW) method. It was found that doping the Co2VSn alloy with rare-earth ions like Eu generates the nonstoichiometric Co2-xEuxVSn and changes its original behavior from half ferromagnetic material to a metallic one. In addition, the total magnetic moment was found to increase with increasing dopant concentration with maximum local magnetic contributions on the Eu-sites. The optical dielectric functions as well as their static value for all the above alloys were also investigated. Moreover, the absorption coefficient, reflectivity and refractive indices were calculated. All the optical calculations were found to agree well with the band structure calculations when determining the alloys' half-metallic behavior. Finally, the nonstoichiometric metallic compounds found in this series might be useful in the flat panel industry as potential phosphors.
