Cerámicos sol-gel de Sm₂O₃:Eu³⁺ obtenidos por el método sol-gel de citrato

Europium doped and mixed with Sm₂O₃ ceramics were obtained from europium and samarium chlorides formation via citrate sol-gel route. This work reports the influence of the europium ions on the structural and luminescent properties of Sm₂O₃:Eu³⁺ ceramics (CIE coordinates) by varying the Eu³⁺ from 10 to 50 mol %. Chemical, structural, and morphological characteristics were established by FTIR and XRD, revealing the presence of characteristics Sm-O vibrational bands of a cubic structure up to 40 mol% Eu³⁺ and a phase mixture of Sm₂O₃ and Eu₂O₃ from 50 mol% Eu³⁺.
