| 摘 要： | 采用溶胶-凝胶法合成了Y2SiO5∶Eu和Y2SiO5∶Tb纳米粉体,使用X射线衍射仪、扫描电镜等对粉体的结构、形貌和发光性能进行了分析,研究了Eu3+和Tb3+不同浓度掺杂硅酸钇纳米粉体的发光性能。在紫外光激发下,所获得的Y2SiO5∶Eu纳米粉体的主发射峰均位于612 nm,对应于Eu3+的5D0→7F2跃迁;Y2SiO5∶Tb纳米粉体的主发射峰均位于540 nm,对应于Tb3+的5D4→7F5跃迁。

| Abstract: | Y2SiO5∶Eu and Y2SiO5∶Tb nanopowders were prepared by sol-gel method.The structure,morphology and luminescent properties were analyzed by X-ray diffraction,scanning electron microscopy and so on.The luminescent properties of Eu3+ and Tb3+ doped yttrium silicate nanopowders with different concentration were investigated.The main emission peak of obtained Y2SiO5∶Eu nanopowders is at 612 nm excited by UV light,ascribed to the transition of5D0→7F2 of Eu3+.The main emission peak of Y2SiO5∶Tb nanopowders is at 540 nm,ascribed to the transition of5D4→7F5 of Tb3+. |
