Optical properties of detonation nanodiamond hydrosols

Studies of the optical properties of hydrosols of 4-nm detonation nanodiamond particles performed in the 0.2–1.1 μm range have revealed a novel effect, a strong increase of absorption at the edges of the spectral range, and provided its explanation in terms of absorption of radiation by the dimer ch...

Summary:Studies of the optical properties of hydrosols of 4-nm detonation nanodiamond particles performed in the 0.2–1.1 μm range have revealed a novel effect, a strong increase of absorption at the edges of the spectral range, and provided its explanation in terms of absorption of radiation by the dimer chains (the so-called Pandey chains) fixed on the surface of a nanodiamond particle. The effect of particle size distribution in a hydrosol on the relative intensity of Rayleigh scattering and light absorption by nanodiamond particles in this range has been analyzed.
