Correction to Germanium-Vacancy Color Center in Diamond as a Temperature Sensor

Quantum nanophotonics with group IV defects in diamond

“…This feature has been recently explored to measure, for instance, temperatures at the nanoscale via all-optical approaches. The methods rely on monitoring the ZPL amplitude, barycentre or full-width at half-maximum of the emitters as the temperature varies [98][99][100] or, in more sensitive realisations, on detecting changes in their fluorescence intensity under anti-stokes excitation-which probes the highly temperature-dependent phonons. 101 Given that SiVcentres can be effectively integrated into atomic force microscopy (AFM) tips, 102 such a method can be a strong contender for all-optical scanning thermometry.…”

Preparations and applications of single color centers in diamond

“…The same year, Hamidreza et al designed and fabricated a dielectric-loaded surface plasmon polariton waveguides embedded a single GeV center to realize remote-control excitation and fluorescence collection of GeV center in a plasmonic chip, and an approximate 6-fold Purcell enhancement compared to the emission in the case of uncoupled GeV was also observed [20]. The other centers in diamond, however, were also proved good performance in the context of quantum sensing that is identical in the case of NV center, and recent example of sensing temperature was achieved via SiV [140], GeV [141], and NE8 [142].…”

Optical Thermometry with Quantum Emitters in Hexagonal Boron Nitride

“…The sensitivities of the hBN nanothermometers presented in this work (cf. Supporting Information Figure S7) is, comparatively, almost 3- and 5-fold higher than those of nanothermometers based on diamond tin vacancy and germanium vacancy color centers . Quantum-dot nanothermometers can reach higher sensitivities, yet their narrow temperature range can prevent their application in realizations requiring monitoring of high temperatures …”
