Field-Induced Assembly of sp-sp2 Carbon Sponges

The formation of macroscale carbon structures characterised by an sp-sp(2)-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 selfassembled 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 sp(2)-carbon systems.

Macroscale carbon structures with sp-sp(2) hybridization characteristics are formed through self-assembly in colloidal solutions under the influence of laser irradiation and electromagnetic fields. The sponge-like morphology, sculpted with gold nanoparticles, is revealed by SEM imaging. The self-assembled sponges are fully characterized for structure and defects using micro-Raman spectroscopy, showing a strong spectral band in the visible range of photoluminescence spectra that is unusual for ordered sp(2)-carbon systems.
