Synthesis and Luminescent Properties of Europium Doped Zirconia Nanoparticles

Abstract:

This paper reports a tunable luminescence of europium (Eu ³⁺) doped zirconia (ZrO₂) nanoparticles as a function of hydrothermal temperature, europium concentrations, time and pH value. The nano-sized Eu doped ZrO₂ (Eu:ZrO₂) particle was synthesized by hydrothermal method at the temperature of 200 °C and time up to 48 h. The nano-sized Eu:ZrO₂ particles have a diameter of about 10 nm. The luminescent properties of nano-sized Eu:ZrO₂ particle was enhanced in the sample when high temperature, high Eu ³⁺ concentration and prolonging hydrothermal time were used at pH 7. These results suggest the use of Eu:ZrO₂ nanoparticles followed by thermal annealing in tuning the luminescence of Eu:ZrO₂ nanoparticles which have potential applications as phosphors in solid state lighting.
