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, Δλ/ΔT= 6.8 GHz/K. Using SiVs in bulk diamond, we achieve 70 mK precision at room temperature with a sensitivity of 360 mathrm{mK/sqrt{Hz}}. Finally, we use SiVs in 200 nm nanodiamonds as local temperature probes with 521 mathrm{ mK/sqrt{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.
