Nitrogen-vacancy (NV-) defects embedded in nanodiamond have attracted attention for their useful photonic and spin properties, and their exceptional photo-stability. Efficiently detecting nanodiamonds that possess colour centres and discriminating from any background fluorescent contamination is essential for nanodiamond-based technologies, and so necessitates the detection of both the nanoparticle and the fluorescent signature. However, optically detecting small nanodiamonds (<40 nnm) proves difficult due to the low absorption and scattering cross section of nanodiamonds. Here we demonstrate an all optical method capable of simultaneous colocalising scattered signal from individual nanodiamonds (~10nm) with the fluorescent signature from NV- centres.
