Abstract

Pure and Eu2+ doped BaAl2O4 phosphors have been synthesized by simple solid state reaction technique. 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:Eu2+ 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.
