【摘要】 用微波辅助水热-煅烧法成功合成了花状NaY（MoO₄）₂颗粒,用XRD、XPS、FESEM进行了表征,提出了花状NaY（MoO₄）₂颗粒可能的形成机理.采用相同的方法合成了NaY（MoO4）₂:Eu³⁺荧光体,该荧光材料在612 nm处有一个强的发射峰,可用作白色发光二极管的红色磷光剂.此外,微波辅助水热-煅烧法可能发展成为制备其他花状稀土钼酸盐的有效途径.更多还原

【Abstract】 Flower-like NaY（MoO₄）₂ particles were synthesized through a microwave-assisted hydrothermal process followed by a subsequent calcination process.The products were characterized by X-ray diffraction,X-ray photoelectron spectroscopy,field-emission scanning electron microscopy.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:Eu³⁺ 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.更多还原
