A blue luminescence glass-ceramics of Eu2+ ions activated Li2O-BaO-B2O3 HUANG Yanlin1,Ho Sueb Lee2,JIANG Chuanfang1,Kiwan Jang2,Eunjin Cho2,WANG Xigang1,QIN Dake1 (1.School of Material Engineering... prepared in air by annealing of the Eu3+-doped Li2O-BaO-B2O3 glass. The as-made glass samples only showed the sharp emission peaks assigned to the transitions of 5D0-7FJ (J=0, 1, 2, 3, 4) of Eu3+ ions......
(1) (2) (3) (4) (5) 2.2 槽电压对电脱氧的影响 在温度为900 ℃时阴极的循环伏安曲线如图5所示.由图5可知:在槽电压低于1.5 V时,未出现还原峰,说明阴极未发生电脱氧反应；当槽电压高于1.5 V时,开始出现还原峰,但不明显,这是导致电还原速率慢,电流低的原因.实际开始发生还原的槽电压应该高于1.5 V. 图5 阴极的循环伏安曲线图 Fig. 5 Cyclic voltampere of cathode 在温度为900 ℃,电解时间为15 h,槽电压分别为1.2,1.6,2.0和2.8 V条件下的阴极产物SEM形貌如图6所示,对应的元素分析如表3所示.由表3可知:当槽......
