ABSTRACT In this report, five systems of varied diameters viz. 62 nm, 85 nm, 115 nm, 160 nm and 450 nm of BaMgAl10O17:Eu2+ nanorods are prepared by solution combustion approach and with annealing at different temperature in reduced atmosphere (N2 + H2). An intense broad blue photoluminescence (PL), corresponding to the electronic transition of Eu2+ from the 4f 6 5d excited state to the 4f 7 ground state, is observed. The blue-shift and enhanced photoluminescence is also observed, and found to be highly dependent on the size of diameter of BaMgAl10O17:Eu2+ nanostructures. The change in decay time and color-coordinates with change in size of diameter of BaMgAl10O17:Eu2+ nanostructure have been analysed and thoroughly discussed.
