Title: | Photochromism of vacancy-related centres in diamond | Authors: | Iakoubovskii, K Adriaenssens, G.J. NESLADEK, Milos |
Issue Date: | 2000 | Publisher: | IOP PUBLISHING LTD | Source: | JOURNAL OF PHYSICS-CONDENSED MATTER, 12(2). p. 189-199 | Abstract: | Optical experiments, involving photoluminescence (PL), the PL excitation and quenching spectra, as well as transmission and its quenching, were used to analyse the photochromic behaviour of some vacancy-related complexes in diamond. The 2.156 eV, 1.945 eV and 1.68 eV optical centres in CVD diamond are attributed to the neutral nitrogen-vacancy, negative nitrogen-vacancy and neutral silicon-vacancy ([Si-V](0)) centres, respectively. Oscillatory behaviour in the excitation spectrum of the 1.68 eV luminescence is observed and from the threshold of the oscillations a position of Ec - 2.05 eV is suggested for the ground state of the [Si-V](0) centre. | Notes: | Katholieke Univ Leuven, Lab Halfgeleiderfysica, B-3001 Heverlee, Belgium.
