Low-temperature studies of Cr3+ ions in natural and neutron-irradiated Mg-Al spinel
(American Institute of Physics, 2020)
Original results on the EPR and photoluminescence Cr3+ ions in natural magnesium aluminum spinel (MgAl2O4) are presented. The photoluminescence spectra of Cr3+ ions in natural MgAl2O4 have been measured before and after ...
Oxidation State and Local Structure of Chromium Ions in LaOCl
(MDPI, 2021)
LaOCl doped with 0–10 mol% Cr was synthesized by thermal decomposition of chlorides. X-ray diffraction (XRD) analysis revealed that incorporation of chromium results in a decrease of the lattice parameter a and a simultaneous ...
Application of Calcium Aluminate Doped with Mn and Cr in Optical Thermometry
(Sciendo, 2023)
Optical thermometers are advantageous for temperature measurement in electromagnetic fields and aggressive environments; however, their composition mostly relies on materials doped with expensive and resource-limited rare ...
