Journal of luminescence Vol. 237. P. 118214 (1-8)Abstract: The spectra of pulsed cathodoluminescence and photoluminescence of synthetic diamonds subjected to radiation-thermal treatment were investigated. The luminescence spectra showed vibronic bands of NV0 centers, interstitials, nickel-nitrogen complexes, as well as previously unidentified bands at 370–380 nm and paired bands at 510 and 532 nm. On the basis of spectral analysis of peaks positions, the 510 and 532 nm bands are assigned to transitions in <100> split self-interstitials (vibronic system 3H) upon interband excitation.
