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 re...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.展开更多

Methods This method considers f licker as a main result of the fundamental frequency component of luminance supe rimposed on the DC-component, the flicker index is defined as ratio between the positive square roots of the sum of the two square components. Results & Conclusion The calculation results of flicker index indicate that flicker can be obviously weakened via increase of subfield number, symmetrical s election and homogeneous interlaced distribution of major weight subfields . Fli cker can be further reduced by choosing the suitable subfield order according to gray scale region of image.展开更多
