•This work studies the structural and photoluminescence properties of europium doped barium carbonate.•Barium carbonate materials have been prepared with high purity.•Our compound has high color purity.•Based on the optical results and CIE chromaticity diagram, the Eu3+ doped BaCO3 phosphor material can be considered as good candidate for red luminescence applications. Nanostructured powders of undoped and europium (Eu3+) doped barium carbonate (BaCO3) were prepared by the autocombustion method. We investigated the influence of Eu3+ doping on the optical properties of barium carbonate. The samples nanostructures were characterized by X-ray powder diffraction (XRD), Scanning Electron Microscopy (SEM), Fourier Transform Infrared Spectroscopy (FTIR), thermogravimetric analysis (TGA) and differential thermal analysis (DTA) and photoluminescence (PL). The results obtained by XRD revealed that the samples consist of the BaCO3 phase with orthorhombic structure having the space group Pmcn, retaining this crystalline phase after doping with Eu3+. These products were found for undoped and BaCO3: Eu3+ nanoparticles with 56–71 nm and 49–60 nm ranges, respectively. SEM reveals that the barium carbonate nanoparticles had a spherical morphology. Symmetric stretches, asymmetric stretches, and in plane bending vibrations, and out of plane of CO32− complexes have detected. The photoluminescence of the obtained BaCO3:Eu3+ were studied. The CIE co-ordinates for the Eu3+ doped BaCO3 were x = 0.580 and y = 0.330. From the CIE chromaticity diagram for the emissions of Eu3+ doped BaCO3. The material has such color purity and reaches 76%. Thus, having color tenability and has been considerate as a candidate of the laser emission.
