通过一步水热化学腐蚀YOHCO3∶Eu胶体微球制备了平均尺寸约为250nm的YVO4∶Eu空心球。利用XRD、SEM、EDS、TEM和PL等手段分别对YVO4∶Eu空心球的结构、形貌和发光性质进行了表征。在280nm紫外光激发下,YVO4∶Eu空心球在618nm处具有较强的红光发射。实验证明,YVO4∶Eu空心球的形成过程为溶液传质过程。

Monodispersed YVO4∶Eu hollow microspheres with average diameters of 250 nm were successfully synthesized by one-pot hydrothermal treatment of YOHCO3∶Eu colloidal spheres.The structure,morphology,and photoluminescence properties were characterized by X-ray diffraction(XRD),scanning electron microscopy(SEM),energy-dispersive spectrometry(EDS),transmission electron microscopy(TEM),and photoluminescence(PL) spectrometer.The formation of the YVO4∶Eu hollow microspheres was revealed to be normal solution transport process.Under ultraviolet(280 nm) excitation,the YVO4∶Eu hollow microspheres showed strong red emission at 618 nm.
