    • Exciton interaction with Ce3+ and Ce4+ ions in (LuGd)3(Ga,Al)5O12 ceramics 

      Khanin, Vasilii; Venevtsev, Ivan; Chernenko, Kirill; Pankratov, Vladimir; Klementiev, Konstantin; van Swieten, Thomas; van Bunningen, Arnoldus J.; Vrubel, Ivan; Shendrik, Roman; Ronda, Cees; Rodnyi, Piotr; Meijerink, Andries (Elsevier B.V., 2021)
      Scintillators based on Ce-doped garnets are regularly co-doped with Mg2+ or Ca2+ to form Ce ions in 4+ state and reduce undesired afterglow. However overly high Ce4+ concentration leads to poor light yield performance. In ...

    • On low-temperature luminescence quenching in Gd3(Ga,Al)5O12:Ce crystals 

      Boháček, Pavel; Krasnikov, Aleksei; Nikl, Martin; Zazubovich, Svetlana G.; Zolotarjovs, Aleksejs (Elsevier B.V., 2019)
      Temperature dependences of the photoluminescence and X-ray excited luminescence intensity and thermally stimulated luminescence glow curves are measured in the 4.2–300 K temperature range for the undoped and Ce3+ - doped ...
