Synthesized BaAl2O4 samples were studied using powder X-ray diffraction analysis (XRD), Photoluminescence spectroscopy (PL), Fourier Transform - Infra Red Spectroscopy (FT-IR) and Scanning Electron Microscopy (SEM). Alkaline earth divalent (Sr, Ca, Zn, Mg) and halides (F, Cl, Br, I) were used as co-dopants to enhance the PL properties of BaAl2O4:Eu 2+ phosphor. Significant impact of ionic radii of co-dopants on PL properties of the phosphor is reported.}, keywords = {BaAl2O4,europium,alkaline earth divalent and halides,photoluminescence}, url = {https://aml.iaamonline.org/article_13851.html}, eprint = {https://aml.iaamonline.org/article_13851_83a482a64f11d7c2642f557fd70d6c42.pdf} }
