Near UV-Blue Excitable Green-Emitting Nanocrystalline Oxide

Figure 4

PL spectra of luminescent powders, –15.0 at % Eu, produced by PACS: (a) excitation spectra for all Eu-doping concentrations at fixed  nm (red) and (b) emission spectra for all powders excited with  nm. The inset shows the highest asymmetry ratio value at 10.0 at % Eu-doping concentration. All measurements performed at room temperature. After RIRO: (c) excitation spectra for all Eu-doping concentrations at fixed  nm (green) and (d) emission spectra for all powders excited with  nm.
