Luminescence properties of Eu(3)(+)-doped Na3Gd(PO4)2 red-emitting nanophosphors for LEDs.

Eu(3+)-doped Na3Gd(PO4)2 phosphors were synthesized by the modified citrate gel combustion technique. From the XRD pattern, structure of the compound was found to be orthorhombic with a particle size of 10-20nm. The emission spectra revealed that the Na3Gd(PO4)2:Eu(3+) phosphors can be excited effectively by 394nm pump wavelength.
