• To improve the emission properties of blue-emitting phosphor layer, SrS:Ce, we evaluated CeN instead of conventional CeCl_3 as a starting material. We evaluated the composition and the crystallinity of the thin films using RBS and XRD methods. We also evaluated luminescent properties of EL devices using SrS:Ce phosphor layer. From the results of RBS and XRD measurements, we found that the concentration of the oxygen impurity in SrS:Ce thin films was decreased and the crystallinity of SrS:Ce thin films was improved when CeN is used. These results mean that the degradation of SrS:Ce thin films can be prevented by the use CeN. The evaluation of luminescent properties, shows that the luminance of SrS:Ce EL device is increased by the use of CeN.
