K. Laganovska*, I. Bite, A. Zolotarjovs, K. Smits In this work we demonstrate a method where by adding Nb ions, Ln3+ ion lumi nescence intensity in HfO2 is increased for up to 15 times (in a sample containing 5mol%Eu). The effect is described as niobium acting as a charge compensator and neutralizing the charge resulting … Continue reading Niobium enhanced Europium ion luminescence in Hafnia nanocrystals
