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.   Photoluminescence of CdSe nanowires grown with and without metal catalyst 期刊论文  OAI收割 nano research, NANO RESEARCH, 2011, 2011, 卷号: 4, 4, 期号: 4, 页码: 343-359, 343-359 作者:  Fasoli A;  Colli A;  Martelli F;  Pisana S;  Tan PH   |  收藏  |  浏览/下载：68/5  |  提交时间：2011/07/05 CdSe  nanowires  photoluminescence  CHEMICAL-VAPOR-DEPOSITION  SHAPE-SELECTIVE SYNTHESIS  LIQUID-SOLID MECHANISM  OPTICAL-PROPERTIES  SILICON NANOWIRES  SI NANOWIRES  ZNSE NANOWIRES  SEMICONDUCTOR NANOCRYSTALS  STRUCTURAL-PROPERTIES  EPITAXIAL-GROWTH  Cdse  Nanowires  Photoluminescence  Chemical-vapor-deposition  Shape-selective Synthesis  Liquid-solid Mechanism  Optical-properties  Silicon Nanowires  Si Nanowires  Znse Nanowires  Semiconductor Nanocrystals  Structural-properties  Epitaxial-growth   Formation of silicon nanocrystals embedded in high-kappa dielectric HfO2 and their application for charge storage 期刊论文  OAI收割 journal of vacuum science & technology b, JOURNAL OF VACUUM SCIENCE & TECHNOLOGY B, 2011, 2011, 卷号: 29, 29, 期号: 2, 页码: article no.21018, Article no.21018 作者:  Li WL;  Jia R;  Chen C;  Li HF;  Liu XY   |  收藏  |  浏览/下载：46/2  |  提交时间：2011/07/05 SI NANOCRYSTALS  MEMORY  TECHNOLOGY  DEPOSITION  VOLTAGE  LAYER  Si Nanocrystals  Memory  Technology  Deposition  Voltage  Layer   Enhanced photoluminescence of Eu3+ induced by energy transfer from In2O3 nano-crystals embedded in glassy matrix 期刊论文  OAI收割 Physical Chemistry Chemical Physics, 2009, 卷号: 11, 期号: 39, 页码: 8774-8778 Y.
