In this paper we have reported synthesis and characterization of Dy3+ and Eu3+ activated Na2Mg(PO4)F, Na2Ca(PO4)F and Na2Sr(PO4)F phosphors. These phosphors were prepared by combustion synthesis and characterized by XRD and photoluminescence techniques. Dy3+ ion gives PL emission in blue and yellow region of the visible spectrum by 385 nm excitation of the LED excitation and Eu3+ ion gives PL emission in the red region of visible spectrum under 251 nm UV-excitation (Hg excitation), respectively. Therefore, above prepared Dy3+ activated phosphors are more applicable for white LED and Eu3+ activated phosphors are more applicable for Hg excitation lamp. Hence prepared, Dy3+ and Eu3+ activated Na2X(PO4)F (X = Ca, Sr, Mg) phosphors by combustion method are very potential application in the field of lamp industry.
