Abstract:
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: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.

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.
