Rare Metals 2013年第5期32卷 490-495页

作者： Yun-Xia Ye Li-Hua wei wei-Chen mei Chen Yin-qun Hua School of Mechanical Engineering Jiangsu University Institute of Laser Technology Jiangsu University School of Material Engineering Jiangsu University

A new Nd3＋-doped organic complex featuring two different perfluorinated carboxylic acids as the first ligand and pyridine derivative 2-amino-3-chloro-5-（tri- fluoromethyl）pyridine as the second ligand was designed and synthesized. Successful coordination between the ligands and central rare earth ions was confirmed by Fourier transform infrared spectroscopy （FT-IR） spectra, 1H nuclear magnetic resonance （1H NMR） spectra, and UV spectra, and the synthesized complex is inferred to be eight-coordinate structure. Solution of the complex dis- solved in DMSO-d6 was prepared and then its fluorescence spectrum, UV-Vis-NIR absorption spectrum, and fluorescence decay curve were tested. The fluorescent lifetime is about 7 txs. Based on the above experimental research, Judd-Ofelt analysis was carried out, and the results indi- cate that appropriate coordination environment around Nd3＋ in this solution results in a high fluorescent quantum efficiency 2 % and a large stimulated emission cross-section about 3.2 × 10^-20 cm^2 at 1,064 nm.

International Journal of Minerals,Metallurgy and Materials 2010年第5期17卷 641-647页

作者： wei-ping Li Xi-mei Wang Li-qun Zhu Wen Li Key Laboratory of Aerospace Materials and Performance （Ministry of Education of China） School of Materials Science and EngineeringBeihang University Beijing 100083 China

An environmentally clean aluminium-based conversion coating on AZ91D magnesium alloy was studied in aluminium nitrate solutions. The morphology, composition, structure, and formation mechanism of the coating were investigated in detail using scanning electron microscopy/energy dispersion spectrometry, X-ray diffraction, transmission electron microscopy, and electrochemical corrosion tests. The results show that the conversion coating is composed of magnesium, aluminium, and oxygen, and shows an amorphous structure. In the initial stage of coating formation, the grain-like nucleus is composed of Al10O15·xH2O, （Al2O3）5.333, Al2O3, AlO（OH）, MgAl2O4, （Mg0.88Al0.12）（Al0.94Mg0.06）2O4, and （Mg0.68Al0.32）（Al0.84Mg0.16）2O4. The conversion coating formed in the 0.01 mol/L aluminium nitrate solution for 15 min can improve the corrosion resistance of the magnesium alloy greatly. The discussion reveals that the possible formation mechanism for the aluminium-based conversion coating is the reduction reaction on micro-cathodic sites due to the electrochemically heterogeneous magnesium alloy substrate.

Chinese Journal of Structural Chemistry 2007年第9期26卷 206-210页

作者： HE Xiao-mei LI Chang-Hong YANG Ying-qun LI wei Department of Chemical Engineering Hunan Institute of Technology Hengyang 421008 China Department of Chemistry and Materials Science Hengyang Normal University Hengyang 421008 China

The title complex （C26H24CuN2O5, Mr = 508.01） has been synthesized by o-methylbenzoic acid, 2,2＇-bipyridine （bipy） and copper perchlorate in the mixed solvent of water and methanol. It crystallizes in orthorhombic, space group P212121 with a = 0.70814（10）, b = 1.6953（3）, c = 1.9539（3） nm, V= 2.3457（6） nm^3, De= 1.439 g/cm^3, Z = 4,μ = 0.971 mm^-1, F（000） = 1052, R = 0.0432 and wR = 0.0860. The structural determination shows that the copper atom is coordinated by three oxygen atoms from two o-methylbenzoic acids and one water molecule together with two nitrogen atoms from 2,2＇-bipyridine, giving a distorted square-pyramidal coordination geometry. The cyclic voltammetric behavior of the complex is also discussed.
