    • Phase stability and oxygen-sensitive photoluminescence of ZrO2:Eu,Nb nanopowders 

      Kiisk, Valter; Puust, Laurits; Mändar, Hugo; Ritslaid, Peeter; Rähn, Mihkel; Bite, Ivita; Jankovica, Dzidra; Sildos, Ilmo; Jaaniso, Raivo (Elsevier B.V., 2018)
      We studied structure and oxygen-sensitive photoluminescence (PL) of ZrO2:Eu,Nb nanocrystalline powders synthesized via a sol-gel route and heat-treated up to 1200 °C. The material containing only 2 at% Eu3+ was predominantly ...

    • Synthesis and vibration spectroscopy of nano-sized manganese oxides 

      Mironova-Ulmane, Nina; Kuzmin, Alexei; Skvortsova, Vera N.; Chikvaidze, George; Sildos, Ilmo; Grabis, Janis; Jankovica, Dzidra; Dindune, Antonija P.; Maiorov, Mikhail M. (Polish Academy of Sciences, 2018)
      X-ray diffraction, micro-Raman and the Fourier transform infrared spectroscopies as well as magnetometry measurements were performed on nanosized manganese oxides to probe their phase composition and magnetic properties. ...
