1Simulation aided hot zone design for faster growth of CZ silicon mono crystals显示文摘Computer simulation was used for optimizing a hot zone for Czochralski (CZ) silicon crystal growth.The heater structure and heat shield material were investigated.With this optimized hot zone,the temperature gradient near the crystal/melt interface increased and the CZ crystal could be grown at a faster rate.It is a great contribution for saving power consumption.CAO Jianwei GAO Yu CHEN Ying ZHANG Guohu QIU Minxiu 2011Rare Metals2011,30,2:13
2Spectrofluorimetric determination of terbium(Ⅲ) by fluorescence enhancement system of Tb-TPA-Triton X-100 by La^(3+)显示文摘The phenomenon of fluorescence enhancement for the system of terbium(Ⅲ) with terephthalic acid (benzene-1,4-dicarboxylic acid (TPA)) in the presence of an excess of La^3+ in Triton X-100 aqueous solution has been studied. The fluorescence intensity of Tb^Ⅲ-TPA system can be greatly increased by La^3+. The intermolecular transfer of energy was responsible for the mechanism of the fluorescence enhancement. Triton X-100 plays an imporlant role for the stabilization of the system. The system, having the maximum excitation and emission wavelengths at 256nm and 546nm, respectively,shows a constant fluorescence intensity over the pH range between 4-6. The fluorescence intensity is a linear function of Tb^3+ concentration in the range of 1.00×10^-8 -2.56× 10^-5 mol·L^-1 and the limit of detection is 5.00×10^-9 mol·L^-1.ZHAO Guohu and ZHAO JunBasic Science Department, Gansu Agricultural University, Lanzhou 730070, China (Received 2002-04-29) 2003Rare Metals2003,22,2:9
3Numerical analysis and simulation of Czochralski growth processes for large diameter silicon crystals显示文摘Numerical analysis and simulation have been an effective means to develop the advanced growth technology and to control the defects type, size and density for silicon crystals of 300 mm and beyond. In the present paper, numerical analysis of the melt flow in the Czochralski (CZ) crystal growth configuration, the three dimensional (3D) modeling, the simulation of melt flow under the magnetic field, the inverse modeling and the time-dependent simulation are reviewed. Fi nally, comparison of numerical analysis with experimental measurements is discussed.TU Hailing XIAO Qinghua GAO Yu ZHOU Qigang ZHANG Guohu CHANG Qing 2007Rare Metals2007,26,6:5
4Preparation and photocatalytic activity of PANI/TiO_2 composite film显示文摘A PANI/TiO2 composite film deposited on the glass surface was successfully prepared using sol-gel dip-coating technique and chemical oxidation method. The film was characterized using XRD, AFM, and UV. The result showed that the TiO2 film consists of both cuboid-shaped and anatase-phased TiO2 nanoparticles. The average grain size of TiO2 in the film was approximately 20 nm. After coating with PANI, the particle was changed into irregular spherical-shaped and the size was increased up to approximately 35 nm in diameter. UV-Vis spectroscopy analysis indicated that the coating of TiO2 with PANI would result in an enhancement of photocatalytic efficiency and an extension of the photoresponse of TiO2. The band gap of the PANI/TiO2 film was 3.18 eV. The photocatalytic property of the film was evaluated by the degradation of rhodamine-B. It was found that 67.1% and 83.2% of rhodamine-B could be degraded under sunlight and UV irradiation within 120 min using the PANI/TiO2 composite film as photocatalyst.GAO Jinzhang LI Shengying YANG Wu ZHAO Guohu BO Lili SONG Li 2007Rare Metals2007,26,1:3

18Spectrofluorimetric determination of terbium with terephthalic acid显示文摘A spectrofluorimetric method has been developed for the determination of terbium(III) based on the formation of a complex with terephthalic acid [benzene-1, 4-dicarboxylic acid (TPA)] in slightly acidic aqueous solution in the presence of gelatin. Terbium ion can form a stable complex with TPA with the stoichiometry of 1:2. The best excitation and maximum emission wavelengths are observed at 260 nm and 545 nm, respectively. The fluorescence intensity of terbium complex gets the strongest within 20 min and remains stable up to 10 h, and it is proportional to terbium(III) concentration in the range of 4.0(10(5-1.6(10(7 mol@L(1 under the optimum conditions. The fluorescence system has good selectivity, sensitivity and stability. The relative standard deviation is still within (4% in the presence of 1200-fold amounts of the other lanthanide ions when the concentration of terbium(III) is 1.0(10(6 mol@L(1 and common co-existing ions hardly interfere the determination. It has been applied to the direct fluorimetric determination of trace terbium (III) in rare earth ores and oxides.ZHAO Guohu and ZHAO JunBasic Science Department, Gansu Agricultural University, Lanzhou 730070, China 2002Rare Metals2002,21,4:1
