AbstractA layered LiNiO2 with high crystallinity was synthesized by sintering the finely prepared mixture of lithium hydroxide and nickel hydroxide in the oxygen atmosphere. The electro-chemical properties of LiNiO2 show that it has a reversible capacity of more than 168mA·h·g-1.It was found that with increasing temperature,LiNiO2 decomposed in air followed with three reaction stages, the apparent activation energies were 747.18±1.0kJ·mol-1,932.46±1.0kJ·mol-1 and 1126.97 ±1.0kJ·mol-1 respectively,and the kinetic equations of the three reaction stages were obtained.

碱土金属铝酸盐系列长余辉磷光体的制备研究=Synthesis of MAl2O4∶Eu2+(M= Ca, Sr, Ba) Phosphors with Long Persistent Luminescence [刊: 中]/翟玉春(东北大学冶金与材料物理化学研究所, 辽宁 沈阳 110004), 张  新, 李建中, 田彦文∥中国稀土学报, 2003, 21(2):205-208

    研究了MAl2O4∶Eu2+(M= Ca, Sr, Ba)磷光体的制备过程, 通过向磷光体中引入微量Dy3+, B3+等添加剂离子, 得到了发绿色光的超长余辉磷光体, 余辉发光初始亮度达4.8 cd·m-2, 激发停止50 h后, 其余辉发光仍清晰可见。 制备出发紫色光、 蓝色光及黄色光的碱土金属铝酸盐系列长余辉磷光体。 分析了各磷光体发射光谱、 激发光谱及余辉发光, 讨论了磷光体的光谱移动以及Eu2+在碱土金属铝酸盐中的发光。 图6  表2  参9
