Abstract
Sulphate based phosphors shows great impact in the field of luminescence in recent times. In the present investigation, Dy3+, Eu3+ activated/co-activated LiNaSO4 phosphor prepared by simple combustion method using urea as a fuel. Phase identification and crystal structure of prepared phosphor is investigated by XRD and Reitveld refinement. Vibrational features of proposed phosphors were confirmed by Fourier Transform Infrared Spectroscopy (FTIR). Morphological study of the proposed phosphor with elemental analysis of the sample is investigated by SEM analysis. Photoluminescence study of the proposed phosphor shows three simultaneous emission peaks in the visible range gives white light emission. These all results confirm that the proposed phosphor is potential candidate for WLEDs and solid state lighting applications.
