Researches from the Institute of Physics CAS (Laboratory of Functional Nanointerfaces and Laboratory of Carbon Nanostructures) developed a simple two-step approach how to control size and purity of HPHT nanodiamonds down to 1 nm from commercially available product by means of air annealing and centrifugation. Characterization and visualization of such small nanodiamonds by Raman spectroscopy...
