Abstract

The luminescence properties and crystalline structure of ZrO₂:Eu nanocrystals doped with different concentrations of Eu were studied. Luminescence from the Eu²⁺ state was not observed even if the electrons and holes were created up to ∼10¹⁹ cm^-3; thus it was suggested the Eu³⁺ was not an efficient trap for electrons possibly due to Eu³⁺ negative charge relative to the crystalline lattice. The mutual interaction between Eu³⁺ ions was not strong up to 5 at.% concentration. The stabilization of ZrO₂ tetragonal as well as cubic structure by Eu³⁺ is possible.
