Synthesis and photoluminescence properties of Eu3+-doped Gd2Zr2O7

Abstract A facile chemical co-precipitation and calcination method has been used to prepare (Gd 1− x Eu x ) 2 Zr 2 O 7 (0≤ x ≤0.100) ceramic particles. (Gd 1– x Eu x ) 2 Zr 2 O 7 ceramic particles were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and photoluminescence (PL) spectroscopy. (Gd 1– x Eu x ) 2 Zr 2 O 7 ceramic particles exhibit a single phase of defect fluorite-type structure. PL spectra show that the characteristic peaks correspond to the f–f transition 5 D 0 – 7 F J ( J =1, 2, 3, and 4) of Eu 3+ . The relationship between the structure of the PL spectra and the host lattice is discussed to identify the changes in intensity for different activation mechanisms.
