In order to confirm the relationship between the luminescence and the ratio of Ce3+/Ce4+ more clearly, a series of YAG:Ce3+ (Yttrium Aluminum Garnet, Y2.94Al5O12:0.06Ce3+) phosphors were pre- pared under different sintering atmosphere. A semi-quantitative analysis based on X-ray photoe-lectron spectroscopy (XPS) was introduced to study the mole ratio of Ce3+/Ce4+ in the as-synthesized YAG:Ce3+ phosphors. The results indicated that the percentage of Ce3+/(Ce3+ + Ce4+) reached 88.46% under the reduction atmosphere. The emission intensity of YAG:Ce3+ phosphors was in-creased significantly with the increasing of Ce3+ concentration.

为进一步认识直流超导限流器中超导带材在直流短路电流下的超导特性及失超电阻的建立规律,对超导带材进行了直流电流冲击实验,测量了冲击电流作用下带材的失超电阻特性,得出了单位长度超导带材失超电阻与其产热量具有固定的函数关系。以此建立了长度可变的超导带材电阻及温升仿真模型,分析了超导带材发生不可逆损伤的原因,并实验验证该模型的可靠性。基于该模型,对5 kV混合型超导限流器中超导组件进行了设计,此方法对其他超导限流器的设计也具有较强的指导意义。
