and Precision Forming, Shanghai Jiao Tong University摘 要:The interfacial reaction between aluminum melt and molten slag under an electric field plays a significant role in aluminum electro-slag refining. Here we studied this interfacial reaction within 680 and 820 ℃ under an electric field between 0 and 9 V. The evolution of aluminum composition was analyzed......
Effect of Li+ ion concentration on upconversion emission and temperature sensing behavior of La2O3:Er3+ phosphorsGuangrun Chen,Ruoshan Lei,Shiqing Xu,Huanping Wang,Shilong Zhao,Feifei Huang,Yin... parameter of La2O3 host and increase the particle size of the samples. The optical investigation shows that co-doping of Li+ ions can enhance the upconversion emission of Er3+ ions in La2O3 matrix......
