All-optical nanoscale thermometry with silicon-vacancy centers in diamond

Abstract

We demonstrate an all-optical thermometer based on an ensemble of silicon-vacancy centers (SiVs) in diamond by utilizing a temperature dependent shift of the SiV optical zero-phonon line transition frequency, $\Delta \lambda /\Delta T=6.8GHz/K$. Using SiVs in bulk diamond, we achieve $70\mathrm{mK}$ precision at room temperature with a sensitivity of $360mK/\sqrt{\mathrm{Hz}}$. Finally, we use SiVs in $200\mathrm{nm}$ nanodiamonds as local temperature probes with $521mK/\sqrt{\mathrm{Hz}}$ sensitivity. These results open up new possibilities for nanoscale thermometry in biology, chemistry, and physics, paving the way for control of complex nanoscale systems.
