Abstract:
The present work is focused on the in-situ characterization of defects in single-crystal diamond induced by 6 MeV carbon ion beam irradiation using ionoluminescence (IL) spectroscopy. The main purpose was to study the optical properties of several defects following the IL evolution and characterize the damage degree using Raman spectra. Three emissions were recorded by IL spectra, located at 430, 504, 575.5 nm with ion fluence in the range of 0∼7 × 1014 cm−2, and were attributed to the A-band, 3H, and NV0 centers, respectively. The 3H centers exhibited a non-monotonic behavior with respect to fluence, with a rapid initial increase followed by a gradual decay. Based on a double exponential model, the data had been well-fitted, and the value of fluence at half of the initial luminescence (F1/2) was found to be notably high (of order 1014 cm−2). A simple Birks-Black model was applied to fit the evolution of the A-band and NV0 centers, and luminescence decays were observed with F1/2 values of (7.9 ± 2.2) × 1011 and (1.2 ± 0.6) × 1012 cm−2, respectively. At the initial stage of irradiation, the intensity decay of A-band and NV0 centers is accompanied by an increase of 3H centers, suggesting that there is a conversion between the defect types.
