Anotace	Negatively charged Si vacancy centres in D have stable PL in the near infrared spectral range (738 nm) which exhibits a very narrow spectral bandwidth. Nanodiamonds with controllable size and surface properties are mandatory for their using in intracellular labelling. We present the fabrication and characterization of individual NDs with Si-V centres prepared from D thin films. Ultrasonication or BASD technique are used to postprocess the D films into NPs of two size distributions, i.e. diameters <100 and 200 nm. The influence of poly- and nanocrystalline film character on NP fabrication and their properties is studied by SEM and PL. We investigate the influence of particle surface termination on their PL properties. Hydrogen termination is provided in H plasma or H atmosphere at elevated temperatures. Oxygen termination is done by air annealing. Finally, Si-V room temperature PL properties of NPs is correlated with their quality (Raman), size distribution and zeta potential.
