Description
The ESR spectrum of two defect centres were observed in finely ground diamond powders (0.5 to 30 μm size). The one centre has been seen before in irradiated and annealed single crystals of natural diamonds (the O1 centre) while the second one has only been seen in synthetic diamonds grown from a nickel-iron melt and is only observable below 250 K. From the study of the variation of the intensity of these lines with size of particles it could be concluded that the O1 centre lies just beneath the surface of these particles and the S centre at least 0.5 μm below the surface.
