Observation of the dynamic Jahn-Teller effect in the excited states of nitrogen-vacancy centers in diamond

Fu, Kai-Mei C; Santori, Charles; Barclay, Paul E.; Rogers, Lachlan; Manson, Neil; Beausoleil, R.


The optical transition linewidth and emission polarization of single nitrogen-vacancy (NV) centers are measured from 5 K to room temperature. Interexcited state population relaxation is shown to broaden the zero-phonon line and both the relaxation and linewidth are found to follow a T5 dependence for T<100K. This dependence indicates that the dynamic Jahn-Teller effect is the dominant dephasing mechanism for the NV optical transitions at low temperatures.
