The results of x - ray photoelectron spectrum ( xps ) demonstrated the ce ions in pure phase ce : yig ( x < 0 . 2 ) were in the state of trivalence . scanning electron microscope ( sem ) analysis showed conglobation of yig and ce : yig particles , whose size were smaller than 1 urn Xps的分析结果显示单相ce ： yig ( x 0 . 2时)中ce离子是以正三价的状态存在，这与物相分析结果是一致的。
