Typical CdSe size series, as obtained through hot-injection based synthesis. Samples are placed under UV excitation to show the concept of quantum confinement: smallest nanocrystals emit in the blue, where the larger crystals emit in the red to near-infrared.
High resolution TEM (Transmission Electron Microscope) image of colloidal nanocrystals. One can literally count the individual atoms in these roughly 3 nanometer sized PbSe crystals.

Welcome

Welcome to the website of the research group ‘Physics and Chemistry of Nanostructures’ (PCN) at the Department of Chemistry of Ghent University, Belgium. The site provides you with information on our research projects, equipment, publications, ... in the field of nanoscience and nanotechnology.

Our research focuses on colloidal nanocrystals, an ideal starting point for multidisciplinary science where chemical synthesis and processing techniques are combined with the characterization and application of physical properties. Our group welcomes collaborations in this field, offering knowhow in synthesis and characterization of a large variety of semiconductor and metal colloidal nanocrystals.

For recent news and upates on the group's activities, we refer to our Twitter account: @NanoUgent .
