A novel red-emitting phosphor LiLaMgWO6 : Eu3+ has been synthesized by a high-temperature solid-state reaction. X-ray powder diffraction (XRD) analysis and FT-IR spectra confirmed the formation of LiLaMgWO6 : Eu3+ phase. The photoluminescence excitation and emission spectra, the concentration dependence of the emission intensity, decay curves, and UV–Vis absorption spectra of the phosphor were obtained. The phosphor could be efficiently excited by the near ultraviolet (NUV) and blue light, exhibiting red light emission. The decay time was also determined for various Eu3+ concentrations in LiLaMgWO6. The calculated color coordinates of the emitted light lie in the red region. Therefore, the obtained results suggest that the prepared phosphors exhibit great potential for use as red emitting phosphor for white light emitting diodes.
