Abstract

Optically active defects in diamond can be excited by photons with an energy less than that of the zero-phonon transition. We show that this process is thermally activated. For diamonds in which one type of defect is dominant, the activation energy is equal to the energy difference between the zero-phonon line and the photons used for excitation.
