Influence of Ce³⁺ on Codoped Y₂O₃: Eu,Ce Phosphor in Luminescence Property and Particle Morphology

Y₂O₃ : Eu and Ce phosphor was synthesized by chemistry and high temperature solid-phase method.XRD analysis and SEM observation manifest that codoped CeCe³⁺ has obvious influence on particle morphology of Y₂O₃ : EuCe³⁺ phosphor.The morphology changed from ball to tube as the concentration of CeCe³⁺ changes.The fluorescence spectra shows that the synthesized phosphor has two main emission bands,which are 614nm of red peak and 587nm.Intensity of 614nm and 587nm emission peak of EuCe³⁺ was enhanced significantly.The physics mechanism in which CeCe³⁺ enhance lighting of EuCe³⁺ is discussed.
