    • Application of Calcium Aluminate Doped with Mn and Cr in Optical Thermometry 

      Rogulis, Uldis; Fedotovs, Andris; Rodionovs, Pavels; Kemere, Meldra; Antuzevics, Andris; Sarakovskis, Anatolijs; Alps, K.; Kiseleva, V. (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 ...

    • EPR characterization of erbium in glasses and glass ceramics 

      Antuzevics, Andris (AIP Publishing, 2020)
      Electron paramagnetic resonance (EPR) is a well-established spectroscopic technique for electronic structure characterization of rare-earth ion impurities in crystalline and amorphous hosts. EPR spectra of erbium-doped ...

    • Oxidation State and Local Structure of Chromium Ions in LaOCl 

      Antuzevics, Andris; Krieke, Guna; Ozols, Haralds; Fedotovs, Andris; Sarakovskis, Anatolijs; Kuzmin, Alexei (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 ...
