Niobium enhanced europium ion luminescence in hafnia nanocrystals
(Elsevier B.V., 2018)In this work we demonstrate a method where by adding Nb ions, Ln3+ ion luminescence intensity in HfO2 is increased for up to 15 times (in a sample containing 5 mol%Eu). The effect is described as niobium acting as a charge ... -
Phase stability and oxygen-sensitive photoluminescence of ZrO2:Eu,Nb nanopowders
(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 ...
