Machine Learning Recognition of hybrid lead halide perovskites and perovskite-related structures out of X-ray diffraction patterns
E. I. Marchenko, V. V. Korolev, E. A. Kobeleva +5
Identification of crystal structures is a crucial stage in the exploration of novel functional materials. This procedure is usually time-consuming and can be false-positive or fals…
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…
Anomalous enhancement of nanodiamond luminescence upon heating
A. A. Khomich, O. S. Kudryavtsev, T. A. Dolenko +4
Characteristic photoluminescence (PL) of nanodiamonds (ND) of very different origin (detonation, HPHT, extracted from meteorite) was studied in situ at high temperatures in the ran…
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…
