	Energy transfer and red phosphorescence in strontium aluminates doped with Cr3+, Eu2+ and Dy3+ (EI CONFERENCE) 会议论文 OAI收割 Dielectrics in Emerging Technologies -and- Persistent Phosphors - International Symposia, May 15, 2005 - May 20, 2005, Quebec City, QC, Canada 作者: Wang X.; Wang X.; Wang X.; Zhang X.; Zhang X. 收藏 \| 浏览/下载：27/0 \| 提交时间：2013/03/25 Cr3+ activated red (694 nm) long persistent phosphorescence originating from 2E-4A2 transition is observed in 4SrO·7Al2O3: Cr3+ Eu2+ Dy3+ system. It is demonstrated that the red phosphorescence is resulted from the conversion of Eu2+ activated blue phosphorescence through persistence energy transfer from Eu2+ to Cr3+. The excitation spectra of the 694 nm emission exhibit strong f-d band of Eu 2+ indicating the existence of the energy transfer. The dependence of lifetimes and intensities of the red and blue emissions on Cr3+ concentrations are studied. The intensity ratio of the red to blue emission bands obtained from photoluminescence spectra is in good agreement with that obtained from fluorescence lifetime measurements. The decay curves of the red phosphorescence at 694nm are also studied.
