Optics and Spectroscopy


Emission spectra and decay kinetics of pulsed cathodoluminescence of a natural IIa-type diamond sample are investigated in the spectral range 340–680 nm. The luminescence of the vibronic N3-system and band A are observed. The N3-system is dominant on a nanosecond scale and has a 415.2-nm zero-phonon line with phonon replicas in the range 430–460 nm. The decay time for the N3 system is found to be 30–50 ns. Structureless band A is observed on a millisecond scale; it has a maximum at 460 nm and a decay time of 8.5–8.8 ms.
