Observation of new vibronic luminescence band in semiconducting diamond

Freitas, J. A.; Klein, P. B.; Collins, A. T.

Steady state and time-resolved photoluminescence studies have been carried out for a new vibronic emission band, with a zero phonon line at 2.395eV, that is observed in type IIb semiconducting diamond. This band exhibits a relatively slow (228ns) photoluminescence decay that is exponential, and is believed to be due to an internal transition at a defect site.
