Mn2+ may occupy Ca2 site (Mn2+(I)) to generate a yellow emission band at 574 nm or Sc3 site (Mn2+(II)) with red emission band at 680 nm. Efficient energy transfers from the green emitting Ce3+ to both Mn2+(I) and Mn2+(II) occur upon blue excitation into Ce3+. Concentration dependence of Mn2+ emission is analyzed based on Ce3+-Mn2+ energy transfer  steady state rate equations  and fluorescence lifetimes. Energy transfer efficiency (nT) and rate (W) are calculated with values as high as 45% and 14.01106 s-1  respectively. 2011 Elsevier B.V.   Co-doping effects of Ca and Ce on the Superconducting Properties in Y1-x Ca (x) (Ba1-y Ce (y) )(2)Cu3O7-delta 期刊论文  OAI收割 JOURNAL OF SUPERCONDUCTIVITY AND NOVEL MAGNETISM, 2012, 卷号: 25, 页码: 805-809 作者:  Ai, Xiaoqian;  Sun, Aimin;  Ma, Ligang;  Zhao, Dongye;  Zhang, Yongfu   |  收藏  |  浏览/下载：22/0  |  提交时间：2018/07/16 Y1Ba2Cu3O7-delta  Ca-doping  Ce-doping  Structure analysis  Superconductivity   Energy transfer in Y3Al5O12:Ce 3, Pr3+ and CaMoO4:Sm3, Eu 3 phosphors (EI CONFERENCE) 会议论文  OAI收割 作者:  Wang L.;  Wang X.-J.;  Zhang X.;  Zhang X.;  Zhang X. 收藏  |  浏览/下载：36/0  |  提交时间：2013/03/25 Non-radiative energy transfers (ET) from Ce3 to Pr3+ in Y3Al5O12:Ce3  Pr3+ and from Sm3 to Eu3 in CaMoO4:Sm3  Eu3 are studied based on photoluminescence spectroscopy and fluorescence decay patterns. The result indicates an electric dipoledipole interaction that governs ET in the LED phosphors. For Ce3 concentration of 0.01 in YAG:Ce3  Pr3+  the rate constant and critical distance are evaluated to be 4.510-36 cm 6 s-1 and 0.81 nm  respectively. An increase in the red emission line of Pr3+ relative to the yellow emission band of Ce 3  on increasing Ce3 concentration is observed. This behavior is attributed to the increase of spectral overlap integrals between Ce3 emission and Pr3+ excitation due to the fact that the yellow band shifts to the red spectral side with increasing Ce3 concentration. In CaMoO4:Sm3  Eu3  Sm 3Eu3 transfer occurs from 4G5/2 of Sm3 to 5D0 of Eu3. The rate constant of 8.510-40 cm6 s-1 and the critical transfer distance of 0.89 nm are evaluated. 2010 Elsevier B.V.
