The persistent spectral hole burning effect has been observed for the nitrogen vacancy (NV) center and the 2.16 eV center in chemical-vapor deposited (CVD) diamond. This sideband is the first observation of spectral hole burning in CVD diamond. Holes are burned in the inhomogeneously broadened zero-phonon lines of both the centers by dye lasers. The holes were observed by photoluminescence excitation spectroscopy, with monitoring of the phonon-sideband emission, at temperatures up to 130 K for the NV center and up to 100 K for the 2.16 eV center.
