摘要: 在水热条件下,用偏硼酸钠作硼源,CH3COONa作缓冲剂,采用丙三醇辅助合成再经过煅烧的方法制备出了花球状的Y3BO6:Eu3+。利用X射线衍射仪、扫描电镜、透射电镜、红外光谱仪、荧光光谱仪等手段对其结构、形貌、发光性能等进行了研究。结果表明,得到的花球的粒度均匀、分散性良好,粒径大约在1μm,是由纳米片组装形成的,CH3COONa和丙三醇在花球的形成过程中具有不可替代的作用。在其发射光谱中,5D0-7F2跃迁占据主导地位,样品具有较高的红橙比。

Abstract: The flower-like Y3BO6:Eu3+ microspheres were prepared through a glycerol-mediated hydrothermal route and followed by a calcination process. Sodium metaborate was used as the source of boron, and CH3COONa was used as "buffer reagent". The crystal structure, morphology and luminescence properties of the prepared products have been characterized by X-ray diffraction, field-emission scanning electron microscopy, transmission electron microscopy, Fourier transform infrared spectroscopy, and photoluminescence excitation and emission spectra. The results indicated that the obtained products were uniform monodisperse flower-like structures with diameter of 1 μm, they were formed by the assembly of nanosheets. The roles of CH3COONa and glycerol were irreplaceable. In the emission spectra of Y3BO6:Eu3+, the 5D0-7F2 transition played dominant role. Therefore, the samples have a high ratio of red-orange.
