A series of new phosphors was prepared using yttrium oxide and the oxides of the iron transition group elements. These phosphors when excited by x- ray radiation are strongly luminescent in the visible spectral region if the oxides of the iron-group oxides contain lanthanide elements. These phosphors were used for the determination of several lanthanides at the ppM level in iron and several of its alloys. Results of the determination of Ce, Pr, Nd, and Sm in low alloy steel are given.
