•BaMoO4:Eu3+ phosphors were synthesized by a facile synthesis route.•PL and CL spectra showed dominant emissions due to (5D0 → 7F2) hypersensitive transitions.•The excitation wavelengths in the UV-B region make BaMoO4:Eu3+ phosphors as a good candidate in the red region for the development of UV-based white LEDs.•PL and CL spectra showed similar CIE values close to the commercially available Y2O3:Eu3+ phosphors.
Eu3+ ions doped BaMoO4 phosphor samples were synthesized by a facile synthesis process. The tetragonal phase of the host lattice was substantiated by the X-ray diffraction patterns. The morphological studies were carried out by taking the scanning electron microscope and transmission electron microscope images and confirmed the formation of shuttle like particles with perpendicular protrusions in the middle of the particle. The single crystalline nature of the phosphors was confirmed by the selected area electron diffraction pattern. The photoluminescence (PL) properties of the Eu3+ ions doped samples revealed good emission with a high asymmetry ratio when excited with ultraviolet B wavelengths (between 280 and 315 nm). The cathodoluminescence (CL) spectra showed similar results to the PL spectra. The calculated CIE values based on the PL and CL spectra were almost similar and confirmed the rich red emission.
