Synthesis and characterization and luminescence property of bis zinc/carbon microspheres composite

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.
