文摘

Double perovskite KLaMgWO₆:Eu3+ phosphors were successfully synthesized by an improved sol–gel method using citric acid and polyethylene glycol as complexing agents. The structure evolution and photoluminescence were systematically invested by X-ray diffraction, Rietveld refinement and fluorescence spectra. The structure of Eu3+ doped samples was double-perovskite with space group C2/m. Enhanced luminescence properties were gotten by adding 5.0 wt% PEG. Na+ with smaller radius was selected to substitute K+ in this novel host. With increasing the concentration of Na+, the tolerance factors decreased and the structure of BO₆ tilted gradually and lowered structure symmetry. Then the emission intensity ratio of 5D₀-sup>7F₂/5D₀-sup>7F₁ transition increased and the red emission played the dominate role. Also the emission intensity was enhanced by increasing the concentration of Na+. The phosphors showed better color purity with better CIE chromaticity coordinates. Therefore the synthesized phosphors is a potential light conversion red material for light emitting diode.
