Abstract
Dy2Ce2O7 nanopowders were synthesized for the first time via solid-state reactions using Ce(NO3)3·6H2O and Dy2O3 as raw materials in a stoichiometric 1:1 Ce:Dy molar ratio. The synthesized materials were characterized by powder X-ray diffraction (PXRD). Structural analysis, performed using the FullProf program with profile matching and constant scale factors, confirmed a predominant cubic Dy2Ce2O7 structure with the Fd-3m space group. Field-emission scanning electron microscopy (FESEM) revealed that the Dy2Ce2O7 particles exhibited uniform spherical morphologies. Ultraviolet-visible (UV-Vis) spectroscopy demonstrated strong light absorption in the UV-visible region. The direct optical band gaps for samples S1, S2, S3, and S4 were determined to be 2.7 eV, 2.6 eV, 2.5 eV, and 2.4 eV, respectively.
