The formation of macroscale carbon structures characterised by an sp-sp2-hybridization is realised by self-assembly in colloidal solutions under an effect of laser irradiation and electromagnetic fields. The sponge-like morphology, sculptured with gold nanoparticles (NPs) was revealed by Scanning Electron Microscopy (SEM) imaging. Full structural and defect characterization of the self-assembled sponges was provided using the micro-Raman spectroscopic technique. The synthesized clusters manifest themselves in the presence of a strong spectral band in the visible range of the photoluminescence spectra that is quite unusual for ordered sp2-carbon systems.
通过在激光辐照和电磁场作用下在胶体溶液中进行自组装,实现了以sp-sp2杂化特征的宏观碳结构的形成。用扫描电子显微镜(SEM)成像揭示了用金纳米颗粒(NPs)雕刻的海绵状形态。使用显微拉曼光谱技术对自组装海绵进行了完整的结构和缺陷表征。合成的团簇在光致发光光谱的可见范围内存在强光谱带,这对于有序的sp2碳系统来说是非常不寻常的。
