Moreover  the obtained polyethylenes were predominately saturated and vinyl-terminated for Fe(II)- and Co(II)-based complexes  respectively. Changing the ligand environment  polymerization parameters also posed a great influence on the catalytic activities and the properties of the resulting polymers. (C) 2014 Elsevier Ltd.

The rare earth compounds were dispersed in the SiO2 colloids and the monodisperse nano-scale composite materials were prepared. The reactant mass fraction and heat treatment temperatures could affect the structures and emission spectrum properties of as-synthesized samples. The samples emit the strong red light upon excitation under the ultraviolet. The main peaks originate from 5D0-7F2 electric dipole transition of Eu3+. With regard to the samples treated at different temperatures  the emission spectra obtained under 266 nm excitation show different shapes of spectra lines and relative intensities  indicating that the Eu3+ ions have been located in different local environments. 2011 Published by Elsevier B.V.   Study of the d-f Emission, and f-d Ground-State and Excited-State Absorption of Nd3+in Crystals Using the Simple Model 期刊论文  OAI收割 SPECTROSCOPY LETTERS, 2010, 卷号: 43, 页码: 423-430 作者:  Duan, Chang-Kui;  Jiang, Sha   |  收藏  |  浏览/下载：15/0  |  提交时间：2018/05/31 f-d transition  Nd3+  excited-state absorption  crystal-field interaction  LiYF4  YPO4   4f(N-1)5d energy levels of lanthanides: a quasi-angular-momentum approach and its application to Cs2NaYF6:Er3+ 期刊论文  OAI收割 CHINESE PHYSICS B, 2009, 卷号: 18, 页码: 1961-1967 作者:  Ma, Chong-Geng;  Jiang, Sha;  Duan, Chang-Kui;  Yin, Min;  Xia, Shang-Da   |  收藏  |  浏览/下载：19/0  |  提交时间：2018/05/31 f-d transition  octahedral site  spin-orbit interaction  coupling of angular momenta   VUV-UV luminescence of magnetoplumbite: (Sr0.96-xBa0.04)Al12-yMgyO19 : Tb-x 期刊论文  OAI收割 JOURNAL OF LUMINESCENCE, 2008, 卷号: 128, 期号: 3, 页码: 476-480 作者:  Zhang, ZY;  Zhang, YH;  Li, XL;  Xu, JH;  Huang, Y 收藏  |  浏览/下载：22/0  |  提交时间：2016/06/28 aluminate  magnetoplumbite  X-ray diffraction  Tb3+  4f-5d transition  VUV luminescence   Recent advances in simple model for 4f-5d transitions of lanthanide ions in solids 期刊论文  OAI收割 JOURNAL OF RARE EARTHS, 2007, 卷号: 25, 页码: 262-267 作者:  Ma Chonggeng;  Reid, M.
