	Synthesis and luminescence properties of Eu3+-doped silicate nanomaterial (EI CONFERENCE) 会议论文 OAI收割 17th International Conference on Dynamical Processes in Excited States of Solids, DPC'10, June 20, 2010 - June 25, 2010, Argonne, IL, United states 作者: Zhang J.; Zhang J.; Zhang J. 收藏 \| 浏览/下载：29/0 \| 提交时间：2013/03/25 In this paper we introduce a sol-gel process for preparing Y 2Si2O7: Eu3+ nanocrystals. 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.
