Novel Phenomenon on Valence Unvariation of Doping Ion in Yb:YAG Transparent Ceramics Using MgO Additives卢忠文1,卢铁城1,2,WEI Nian1,MA Benyuan1,ZHANG Wei1,LI Feng1,GUAN Yongbing11. Department of Physics... results showed the valence variation of doping ion Yb3+ would not appear when adding MgO as sintering additives, so ceramics showed colorless transparent instead of green due to Yb2+ color center using......

Influence of annealing on spin state of cobalt ions inLa1-xSrxCoO3 (0≤x≤0.5) system JIANG Lizhen1,XU Zhuan2 (1.College of Information and Electronic Engineering, Zhejiang Gongshang University... determined, and their variations with Sr doping and oxygen annealing condition were obtained. The result suggested that by assuming that the Co3+ ions were in the intermediate-spin (IS) state, most......

. They are not lithium manganate apparently with black color. As more Li+ inserts into the Mn-O structure overtime, the Mn will be oxidized to the valence state of Mn4+ under strong alkaline condition. Since an average valence state of Mn3.5+ is preferred for LiMn2O4, 15 min of SH reaction time can be long enough for the proposed LiMn2O4 preparation route. The SEM images of LiMn2O4 prepared with different SH......
