Luminescence properties of nitrogen-vacancy centres in nanodiamond as a function of size
Original language description
Biomedical monitoring using fluorescent nanodiamonds (fND) as cellular marker require specific fND size, depending on the particular application. Fluorescence in fNDs depends not only on the number and type of the colour centres, but for very small ND itis related to the fND size effects. In this work we concentrate on such size dependence of photoluminescence (PL) properties of fNDs (Petráková 2012). Particles used are fNDs of size range from 8 - 120 nm, prepared from Ib synthetic diamond. The size fraction of 8-50 nm fNDs was separated by centrifugation and used for single particles measurements by drop casting. Size distribution was confirmed by atomic force microscopy (AFM) and dynamic light scattering (DLS). AFM/Raman system was used to study single particles. We model mathematically the NV-/NV0 luminescence and discuss luminescence stability of single particles as a function of their size.
