Synthesis of rod shaped BAM nano-phosphors by a liquid phase precursor method and their luminescence properties

Blue emitting Eu2+ doped barium-magnesium aluminate (BAM) nano-phosphors were synthesized using liquid phase precursor (LPP) method corresponding to Ba0.87-0.90Mg0.91-1.0Al10O17-17.05: Eu0.05. The phosphor particle size, morphology and crystallinity were characterized by FESEM and X-Ray diffraction analysis. The effects of composition and particle size on the luminescence efficiency were investigated by employing photoluminescence spectroscopy. The rod shaped phosphor particles ~60 nm in diameter and 400-700 nm in length were obtained. The phosphor particles emission peaks shifted towards a longer wavelength with 80% luminescence intensity compared with the commercial BAM.
