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.   Theoretical elastic stiffness, structural stability and thermal conductivity of La(2)T(2)O(7) (T = Ge, Ti, Sn, Zr, Hf) pyrochlore 期刊论文  OAI收割 Acta Materialia, 2010, 卷号: 58, 期号: 13, 页码: 4369-4377 B.
