Influence of MCCA on structure and photoluminescence of Eu2+ doped BaMgAl10O17 nanophosphor for use in active displays

Abstract In this letter, experimental results on structure and photoluminescence (PL) properties of Eu2+-doped BaMgAl10O17 (BAM:Eu2+) nanophosphors modified by a distinctive morphology control chemical additive (MCCA) namely, ammonium fluoride are reported. X-ray diffraction confirmed hexagonal phase with p63/mmc space group whereas, scanning electron microscopy images revealed layered rod-like morphologies for the MCCA modified BAM:Eu2+ nanophosphors. Upon excitation at 300 nm, the room-temperature PL showed enhanced emission peak at ~467 nm attributed to 4f65d1 → 4f7 transition of Eu2+ ions with (0.22, 0.17) as color coordinates. The obtained results suggest that MCCA modified BAM:Eu2+ nanophosphors would be suitable for active displays and lighting devices.
