Preparation and Luminescent Properties of Nancrystalline Zro₂:Eu³⁺ by Emulsion Method

Abstract:

Europium-doped nanocrystalline ZrO₂: Eu³⁺ powders with different doped concentrations were prepared by emulsion processing method, with different doped concentration and calcination temperature on the material grain size, structure, size and luminescent properties. The results show that: Eu³⁺ has a stabilizing effect on tetragonal phase of ZrO₂. Emission spectra indicates that the main emission peak in the 593m and 608m, “Blue Shift “will occur in 5D₀ → 7F₂ transition of the emission spectra of sample with the sintering temperature at 1000°C. Samples with the sintering temperature soaring, spectral emission intensity also increases.
