XRD Analysis on the Fluorescence Material of Sm Doped Si-Ca-Mg System

引用

Chinese Journal of Structural Chemistry 2007年第8期26卷 902-906页

作者： huang qing-Ming Instrumentation Analysis and Measurement Center of Fuzhou University Fuzhou Fujian 350002 China

Fluorescence material of Sm doped Si-Ca-Mg system was synthesized by using the method of solid phase reaction at high temperature. The phase composition and crystal structure of this material were analyzed with XRD method for its composition and the existence form of Sm atom. We aimed to exactly determine the phase composition of this fluorescence material and the doping position and environment of rare-earth Sm atom in the system because these factors have significant effects on the properties. The analytical results show that the Sm atoms dope in Ca2O26Si6Sm8 lattice in the form of atomic site-occupation in three different space positions with different occupancy rates. Therefore, based on the XRD analytical results, the fluorescence material of Sm doped Si-Ca-Mg system with high performance can be synthesized.

QE-integrating framework based on Github knowledge and SVM ranking

引用

Science China(Information Sciences) 2019年第5期62卷 92-107页

作者： qing huang Huaiguang WU School of Computer and Information Engineering Jiangxi Normal University School of Computer and Communication Engineering Zhengzhou University of Light Industry

The latest query expansion(QE) methods use the software development features for expanding queries. However, these methods allow only one feature to be considered at a time. To consider additional features simultaneously, we propose a QE method based on Github knowledge; this is a new comprehensive feature that covers both the existing features(i.e., the application program interface(API) information and crowd knowledge). It is extracted from the "pull requests" of code repositories on Github, which contain descriptions of a request and its commits, the participants’ comments and the API information of the changed files. In addition, we implement a black-box framework that integrates multiple QE methods based on the support vector machine ranking called Github knowledge search repository(GKSR). Our empirical evaluation shows that the GKSR outperforms the state-of-the-art QE methods CodeHow and QECK by 25%–32% in terms of precision.

Upconversion （UC） phosphor Tm3＋ doped YF3 nano-erystals were prepared by hydrothermal method under different conditions and characterized by Field Transmission electron microscopy （TEM）, Scanning electron microscopy （SEM） and X-ray diffraction （XRD）. Their UC luminescence properties were studied by fluorescence spectrophotometer with 980 nm diode laser excitation, and impact of different grain sizes and morphology on the UC luminescence intensity was discussed. The fluorescence decay lifetime was calculated by Multi-exponential function fitting method. Results show that UC emission intensity was enhanced with the reduction of grain size, and the decay lifetime is 0.60 us.

Crystallization Behavior of Polymer Derived Silicon Carbide Sintered Through Microwave Heating Technique

引用

Journal of Wuhan University of Technology(Materials Science) 2017年第6期32卷 1368-1373页

作者：熊俊 huang qing School of Materials Science and Engineering Tianjin University Tianjin 300072 China

A self-crosslinkable liquid highly branched polycarbosilane（LHBPCS） with 5.07% vinyl group and a C/Si ratio of 1.33 was used as the precursor to prepare Si C ceramic material. Microwave heating technique and conventional heating method were applied for the heating treatment process. It was found that, compared with conventional heating method, microwave heating technique could enhance the crystallinity of Si C ceramic material with small grain size at much lower curing temperature and within shorter time. In addition, the SiO_2 additive could lead to less α-Si C and excess carbon, but worsen the crystallinity of β-Si C in the final samples.

Spinodal surface instability of soft elastic thin films

引用

Acta Mechanica Sinica 2008年第3期24卷 289-296页

作者： Shi qing huang Xi Qiao Feng Department of Engineering Mechanics Tsinghua University Beijing 100084 China

When the thicknesses of thin films reduce to microns or even nanometers, surface energy and surface interaction often play a significant role in their deformation behavior and surface morphology. The spinodal surface instability induced by the van der Waals force in a soft elastic thin film perfectly bonded to a rigid substrate is investigated theoretically using the bifurcation theory of elastic structures. The analytical solution is derived for the critical condition of spinodal surface morphology instability by accounting for the competition of the van der Waals interaction energy, elastic strain energy and surface energy. Detailed examinations on the effect of surface energy, thickness and elastic properties of the film show that the characteristic wavelength of the deformation bifurcation mode depends on the film thickness via an exponential relation, with the power index in the range from 0.749 to 1.0. The theoretical solution has a good agreement with relevant experiment results.
