Synthesis and characterization and luminescence property of bis(8-hydroxyquinoline)zinc/carbon microspheres composite

利用流变相反应法制备了碳微球（CMSs）负载8-羟基喹啉锌（Znq2）的复合材料。通过场发射扫描电子显微镜、X射线衍射仪、热重分析仪、X射线光电子能谱仪、傅里叶红外光谱仪和荧光分光光度计等对Znq2/CMSs复合材料结构和发光性能进行了表征和分析。结果表明：Znq2以非共价键形式负载于直径均匀的CMSs（300~400 nm）表面,形成了一种Znq2/CMSs复合材料,该复合材料在黄光（540 nm）区发光,有望应用于有机电致发光领域。

The composites of bis（8-hydroxyquinoline） zinc（Znq2） and carbon microspheres（CMSs） were synthesized by rheological phase reaction.Their structure and photoluminescence property were characterized by the field emission scanning electron microscopy,X-ray diffraction,thermogravimetry,X-ray photoelectron spectroscopy,Fourier transformation infrared absorption spectrometry and fluorospectrophotometer.The results show that Znq2 is loaded on the surfaces of uniform CMSs with 300~400 nm in diameters in the form of non-covalent bond and the peak wavelength of the composite is 540 nm in photoluminescence spectra.It is expected to apply in the field of organic electroluminescence for Znq2/CMSs composite.
