Abstract：Eu3＋-doped NaY(MoO4)2 and Na(Y, Gd)(MoO4)2 phosphors were prepared via microemulsionhydrothermal method. X-ray diffraction (XRD), scanning electron microscopy (SEM) and fluorescence spectroscopy were used to characterize the samples. The XRD of as-prepared sampleswere in agreement with the PDF # 82-2369 of NaY(MoO4)2. SEM images showed that the as-prepared particles had a diameter size ranging from 0.5 to 0.8 μm. The critical activator molar concentration (Eu3＋) in NaY(MoO4)2∶Eu3＋was 4%, and the luminescent intensity of Na(Y, Gd)(MoO4)2∶4%Eu3＋was maximum when Y∶Gd molar ratio at 0.5∶0.5. Excited by 276, 395 and 465 nm, Na(Y0.48, Gd0.48)(MoO4)2∶4%Eu3＋exhibited pale pink, yellow and orange-red respectively. The sample of Na(Y, Gd)(MoO4)2∶Eu3＋could become a valuable luminescent material for white LED.
