Abstract

Abstract: ZrO2 :Eu 3+ nanocrystals were synthesized by hydrothermal technique. Effects of Eu 3+ -doping and annealing on the morphology, crystal structure and fluorescence properties of the resultant ZrO2 :Eu 3+ nanocrystals were investigated. The morphology and crystal structure of the ZrO2 :Eu 3+ nanocrystals were characterized by TEM, XRD, FT-IR and Raman, respectively. The fluorescence properties were explored by PL and decay curve. The results showed that both the Eu 3+ doping concentration and annealing temperature had influence on the crystal structure and fluorescence properties of ZrO2 :Eu 3+ nanocrystals. For the low Eu 3+ -doping concentration, the amount of the tetragonal phase decreased with increasing the annealing temperature. The Eu 3+ ion is trivalent rare earth (RE 3+ ) activator, which can stabilize the tetragonal as well as the cubic structure of ZrO2 . The ZrO2 :Eu 3+ nanocrystals with tetragonal or cubic structure may find potential applications as the raw material for producing the transparent ceramics with efficient fluorescence properties.
