BaSO4:V5+ synthesized at 1000°C in air exhibits an intense emission band peaking at 495 nm from surface traps assisted by atmospheric oxygen on excitation at 350 nm due to charge transfer from O2− to V5+ in the (VO4)3− tetrahedral complex. BaSO4:Eu synthesized under similar conditions exhibits both Eu2+ (375 nm) and Eu3+ (619 nm) fluorescence. Vanadium codoping quenches the Eu2+ fluorescence but enhances the Eu3+ fluorescence in BaSO4:V, Eu due to charge compensation. However, Eu codoping quenches the vanadium fluorescence by diffusion of vanadium into the crystal, and V2O5 also serves as a flux enhancing Eu3+ doping efficiency in BaSO4 lattice. The 619nm Eu3+ PL emission intensity in BaSO4:V5+, Eu3+ is comparable to 592nm emission from commercial (Y,Gd) BO3:Eu3+. However, V5+ emission shows strong thermal quenching, while Eu3+ emission shows little thermal quenching up to 210°C, making BaSO4:V5+, Eu3+ a promising new red phosphor for improving the color rendering of blue light‐based white LED. The ratio of Eu3+ to V5+ fluorescence increases with excitation temperature (30°C°C–180°C) enabling BaSO4:V5+, Eu3+ to be used as a non‐contact luminescence thermometer.
