| Abstract: | Y2O3 : Eu and Ce phosphor was synthesized by chemistry and high temperature solid-phase method.XRD analysis and SEM observation manifest that codoped Ce3+ has obvious influence on particle morphology of Y2O3 : Eu3+ phosphor.The morphology changed from ball to tube as the concentration of Ce3+ 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 Eu3+ was enhanced significantly.The physics mechanism in which Ce3+ enhance lighting of Eu3+ is discussed. |
