Abstract
Near ultra violet (NUV) excited and red-emitting LiSrPO4: Eu3+ phosphor for (White Light emitting diode) W-LED application with the varying concentration of Eu3+ was successfully prepared by solid state diffusion method. The structural confirmation of prepared phosphors was done by using X-ray diffraction (XRD) analysis and photoluminescence (PL) properties of LiSrPO4: Eu3+ showed emission corresponding to 5D0→7F1and 5D0→7F2 transitions with the major peak at around 620nm. The concentration quenching value Eu3+ ion in LiSrPO4: Eu3+ phosphor prepared by solid state diffusion method was observed at 0.03mol.
