Abstract

Eu3+ activated NaLa(WO4)2 (NLW) red phosphors were synthesized via an ethylene glycol route at low temperature as 120 °C for solid state lighting applications. X-ray diffraction (XRD), field emission scanning electron microscope (FE-SEM), FT-IR, Raman, emission and excitation properties were studied for synthesized NLW phosphors. XRD analysis endorsed the formation of NaLa(WO4)2 with scheelite structure. For 9 mol% of Eu3+ concentration, the phosphor demonstrates an intensified narrow excitation peak at 394 nm indicating a strong absorption due to Eu3+ ion. The PL emission spectra of NaLa(WO4)2:0.09 Eu3+phosphors exhibited an intense peak at 615 nm (red) which agrees to 5D0→7F2 transition of Eu3+ at the excitation wavelength of 394 nm. The CIE colour coordinates of NaLa(WO4)2:0.09 Eu3+ red phosphor accord very well with the standard values of NTSC. The sterling luminescent properties of NaLa(WO4)2:0.09 Eu3+ phosphor executes it as a potential red phosphor upon near-UV LED excitation.
