摘　　要：Flower-like NaY（MoO4）2 particles were synthesized through a microwave-assisted hydrother- mal process followed by a subsequent calcination process. The products were characterized by X-ray diffraction, X-ray photoelectron spectroscopy, field-emission scanning electron mi- croscopy. The possible formation mechanism of the flower-like NaY（MoO4）2 precursor was proposed. The NaY（MoO4）2：Eu3＋ phosphors were also prepared and their luminescence properties showed the NaY（MoO4）2：Eu^3＋ materials with the emission peak at 612 nm had potential application as a red phosphor for white light-emitting diodes. Furthermore, the microwave-assisted hydrothermal process followed by a subsequent calcination process could be extended to prepare the other lanthanide molybdates with the flower-like morphology.
