Exsolution of oxygen impurity from diamond lattice and formation of pressurized CO2-I precipitates
Andrei A. Shiryaev, Yurii Chesnokov, Alexander L. Vasiliev +1
Diamond single crystals showing Infra-red features of pressurized CO2-I phase were studied using Transmission Electron Microscopy (TEM) and tomography. Numerous O-containing precip…
Temperature dependence of Fano resonance in nanodiamonds synthesized at high static pressures
A. A. Shiryaev, E. A. Ekimov, V. Yu. Prokof'ev +1
Temperature dependence of Fano resonance, recently discovered in infra-red (IR spectra of nanodiamonds synthesized from chloroadamantane at high static pressures, is investigated.…
Structural peculiarities, mineral inclusions and point defects in yakutites -- a variety of impact-related diamond
Andrei A. Shiryaev, Anton D. Pavlushin, Alexei V. Pakhnevich +3
An unusual variety of impact-related diamond from the Popigai impact structure - yakutites - is characterized by complementary methods including optical microscopy, X-ray diffracti…
Formation and characterization of an Al-rich metastable phase in Al-B phase diagram
A. I. Malkin, V. V. Chernyshev, A. A. Ryazantseva +3
Vacuum heat treatment of mechanically-alloyed powders of boron and aluminum leads to formation of a metastable Al-rich phase, which can be quenched. Its structure, composition, and…
Photoluminescence of silicon-vacancy defects in nanodiamonds of different chondrites
A. A. Shiryaev, A. V. Fisenko, L. F. Semjonova +2
Photoluminescence spectra show that silicon impurity is present in lattice of some nanodiamond grains (ND) of various chondrites as a silicon-vacancy (SiV) defect. The relative int…
Small-Angle X-ray and neutron scattering from diamond single crystals
A A Shiryaev, P Boesecke
Results of Small-Angle Scattering study of diamonds with various types of point and extended defects and different degrees of annealing are presented. It is shown that thermal anne…
