Color center in nanodiamonds

We are aiming to establish color centers in nanodiamonds as a new building block for solid- state based quantum technology. Our vision is to obtain single color center per one, few tens of nanometer sized, nanodiamond with atom-like optical properties. In our research we employ advanced diamond growth and surface treatment in combination with resonant and off-resonant excitation to isolate single color centers.
