CONDUCTIVE DIAMOND PARTICLES, CONDUCTIVE DIAMOND ELECTRODE, AND TESTING DEVICE

摘要

Provided are conductive diamond particles including: particulate bases; and boron-doped diamond films on at least part of surfaces of the particulate bases, wherein an average particle diameter of the conductive diamond particles is greater than 0.5 micrometers, and wherein in Raman spectrum measurement of the conductive diamond particles at an excitation wavelength of 532 micrometers, a ratio of an intensity of the conductive diamond particles at 1,580 cm^−1 to an intensity of the conductive diamond particles at 1,332 cm^−1 is less than 0.090.
