    Tunable Eu2+ emission in KxNa1-xLuS2 phosphors for white LED application

  • Original language description

    Set of Eu2+-doped KxNa1-xLuS2 phosphors (x = 0–1) in the form of transparent crystalline hexagonal platelets was successfully synthesized by chemical reaction under the flow of hydrogen sulfide. Their physical properties were investigated by means of X-ray diffraction, X-ray fluorescence, time-resolved luminescence spectroscopy and electron paramagnetic resonance. Special attention was given to photoluminescence emission spectra under the 395 nm and 455 nm excitation aiming to obtain white emission with tunable color temperature. EPR method was employed to understand the Eu2 + incorporation and distribution in the KxNa1-xLuS2 hosts. CIE xy-coordinates were calculated to compare effects of different K/Na concentration in KxNa1-xLuS2 on resulting spectrum. The application potential of mentioned compounds in the field of white LED solid state lighting phosphors is thoroughly discussed.
