Abstract

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.
