摘要: Flat silicon nanocrystals coated with the perfluorophenyl ligands have been obtained. are formed due to specific interactions between ligands. The fact of binding surface nanoparticles is supported by XPS and FTIR spectroscopy. Morphology structure synthesized Si-nanoparticles were studied using transmission electron microscopy. samples comprise two types nanoparticles: spherical flat (2D structures). Electron diffraction pattern demonstrates that amorphous. spot patterns observed for which crystalline structure. size these particles varies from 15 50 nm. thickness was evaluated atomic force microscopy; it appeared be close 3.3 nm in average. Small large interrelated; plates products aggregation crystallization small nanoparticles. Nanocrystals exhibit photoluminescence emission maximum at 430
