Abstract
The Er3+/Nd3+ codoped BaMgAl10O17:Eu2+ phosphor nanoparticles have been synthesized through solution combustion method. Nanophosphor has shown intense broad blue photoluminescence (PL), corresponding to the 4f65d→4f7 electronic transition of Eu2+ ion under vacuum ultraviolet (147nm) as well as UV (355nm) excitations. An enhancement in blue emission of Eu2+ has been observed on the codoping of Er3+/Nd3+ ions and concentration of the doping ions have been optimized. Lifetime of the 4f65d→4f7 transition has been measured and discussed. The enhancement in emission intensity of codoped blue nanophosphor is explained by energy transfer from the Er3+/Nd3+ ions and created defect states to the Eu2+ in the BaMgAl10O17. This phosphor has also shown better emission intensity as compared to commercial blue phosphor under VUV excitation and thus making it attractive for the application in plasma display panels and mercury free-fluorescent lamps.
