Abstract

A simple and mild chemical co-precipitation and calcination method has been used to prepare (La_1-xEu_x)₂Zr ₂O₇ (0 ≤ x ≤ 0.100) particles in different crystallization states. The products were characterized by X-ray diffraction and photoluminescence spectroscopy. The calcination temperature is closely related to the crystallinity of the products. PL spectra display that the characteristic peaks of (La_1-xEu_x)₂Zr₂O ₇ correspond to the f-f transition ⁵D₀- ⁷F_J(J = 1,2,3, and 4) of Eu³⁺. The influence of the degree of crystallization on structure of PL spectra was proposed. The variations in intensity of PL spectra for different activation mechanisms were also discussed.
