摘要: 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。

Abstract: 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.
