METHOD OF DETECTION OF THE ANGLE OF DISORIENTATION OF DIAMOND CRYSTALLITES IN DIAMOND COMPOSITE

摘要

1. A method for determining the angle of disorientation of diamond crystallites in diamond composite comprising diamond composite placement in electron spin resonance spectrometer resonator (ESR), the measurement of ESR spectra nitrogen-vacancy defect in the NV-diamond composites with different relative orientations of the composite diamond external magnetic field, a comparison of the obtained dependencies EPR line with the provisions of the ESR calculated NV-line defect in a diamond single crystal in a magnetic field determined by the relationship: B = B ± / D (3Cosθ-1), where B = hf / gβ- were magnetic field rank, which determines the center of gravity of the ESR spectrum, T; h = 6,62606896,10- Planck constant, J · s; f - frequency of the EPR spectrometer Hz; g = 2,0024 - dimensionless quantity called the g-factor and characterizing the gyromagnetic ratio for the electron magnetic moment NV-defect in diamond; β = 9,2740 · 10- Bohr magneton, J / T; D = 0,104 - splitting patterns for fine NV defect in diamond, T; Θ - angle between the magnetic field and axis 111 crystal diamond, degrees, determining increasing the width of the ESR line in the composite diamond compared to the width of the ESR line in m onokristalle diamond and determining the angle of disorientation of crystallites in diamond composite diamond EPR.2 to increase linewidth. A method according to claim 1, characterized in that the measurement of ESR spectra NV-defect is carried out by optical detection of magnetic resonance (ODMR) NV-defektov.3. A method according to claim 2, characterized in that the excitation of the diamond NV-defects is carried out using confocal optics.
