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