Figure 1: The figure shows measured Raman spectra of the original NDs, the NDs after Fe implantation and the NDs after implant and annealing.

From: Fe doped Magnetic Nanodiamonds made by Ion Implantation

Figure 1

The original NDs had a diamond peak at 1332.5 cm−1 and a broad peak at 1579 cm−1, which is probably due to surface graphitic structure. After annealing, the diamond peak restored to the original position of 1332.4 cm−1 and the FWHM was reduced to 11.1 cm−1.
