Enhancement of photoluminescence of Ba2SiO4:Eu2+ by co-doping of La3+ or Y3+ HU Xiaoye1,LI Yongxiu1,LI Zhenhua1,XU Xin1 (1.Research Center for Rare Earths & Nano/micro Functional Materials... technique in reductive atmosphere (a mixture of 5% H2 and 95% N2). The results showed that the co-doping of La and Y could greatly enhance the fluorescence intensity of Ba2SiO4:Eu2+ phosphors......
Preparation and property of spinel LiMn2O4 material by co-doping anti-electricity ions XIAO Jin(肖 劲), ZHU Hua-li(朱华丽), CHEN Zhao-yong(陈召勇), PENG Zhong-dong(彭忠东), HU Guo-rong(胡国荣) School... fades. The results of cyclic voltammetry indicate that the shape of two couples of redox peaks of the material synthesized by co-doping anti-electricity ions is more integrate and symmetrical than......
stability of brookite phase is improved greatly after co-doping, indicating that the co-doping facilitates the phase stabilization. Co-doping can improve the photodecoloration activity of composite brookite TiO2. Key words: co-doping; brookite titania; photocatalysis  ......
Influences of Co-Doping Cation on Properties of PWO∶F- Scintillating Crystal Fan Yuhong1,Ge Yuncheng1,Zhang Chunsheng1,Zhang Mingrong1 (1.Crystal Laboratory, Beijing Glass Research Institute, Beijing 100062, China) Abstract:Whereas the light yield of PWO crystal can be significantly improved by doping with either of F- and Sb3+, effects of heavily co-doping with by F-+Sb3+, F-+Ca2+, and F-+Ca2......
油藏描述的发展与应用尚静,施超长江大学地球科学学院摘 要:随着各个油田不断开采,其产量也在逐渐降低,开采难度越来越高,相应的石油开采技术不断提高,由此诞生了油藏描述这一技术,该技术是为解决油田开采开发的实际问题而产生的.近几十年来,油藏描述技术发展迅速,经历初期,中期,精细期,其内容从简单,单一到多元,复杂,已成为现代油气田开发的重要技术手段之一.我国陆相油田地质条件复杂,在不同的开发阶段,所拥有的资料不同,应用的任务也不相同,油藏描述的任务,要求,精细度也不相同,每个阶段都在地质,构造,建立模型的侧重点上......
of thermoelectric materials. Herein, we report the effects of Sm and S co-doping on thermoelectric transport properties of copper antimony selenides in the temperature range of300 K < T < 650 K. Through the Callaway model, it demonstrates that Sm and S co-doping induces strong mass differences and strain field fluctuations in Cu3 SbSe4. The results prove that doping with suitable elements can......
Co-doping Effect on Microstructures and Ionic Conductivity of Aliovalent Cations Modified Ceria CHOU Chen-chia1,YEH Tsung-her1 (1.Advanced Ceramics Laboratory, Department of Mechanical Engineering... at 650℃ (0.0105 S/cm). Co-doping Mg2+ and Gd3+ is found to increase the ionic conductivity of ceria and hence decreases the operation temperature as well as the cost of solid oxide fuel cell (SOFC). 关......
