as well as display devices. Comparison of as-synthesized phosphors with standard phosphor used in CFL(compact fluorescent lamp) was also done. Energy transfer mechanism of Gd3+ to Eu3+ was also......
by the degradation of methylene blue(MB) equipped with a 300 W medium pressure mercury lamp. Results show that the first order reaction rate constants of Lu3+/TiO2 and pure TiO2 are0.0565 and 0.0263......
extraction in hydrometallurgical processing.For this reason,the goal of this work is to evaluate the use of FactSage 7.2 software for the leaching of fluorescent lamp powders by sulfuric acid.The effect......
by FTIR, 1H NMR and TGA analysis. The resist formulated with PTBCHNB and cast in THF solution showed square pattern of 10 μm×10 μm using a mercury-xenon lamp in a contact printing mode and tetramethyl......

火焰-原子荧光光谱法测定微量金的研究刘德林1,高树林2,黄炼2(1.吉林省通化市吉林省有色金属地质勘查局六六队2.北京金索坤技术开发有限公司)摘 要:介绍了火焰-原子荧光光谱仪测定微量金的方法,研究了灯电流,光电倍增管负高压,燃气和辅助气流量,光源所激发原子化器上火焰位置与干扰的关系等对测定结果的影响,找出了测定微量金的最佳条件.该方法具有操作简便快速,基体干扰少,灵敏度高等优点,其最低检出限为0.000 2μg/mL,测定结果令人满意.关键词:火焰-原子荧光光谱法; 微量金; 检测方法......
the UV lamp when the matrix is in a proper ratio of two phases, which suggests that the heterostructure between the two crystals(BaMSiO4 and Ba2 MSi2 O7) improves the self-reduction process......
desertification climate, and the materials were analyzed and characterized by UV-Vis, SEM, FTIR and XRD measurements. Moreover, a UV carbon arc lamp was used to test the resistance to aging. The experimental......
