The multi-source depostion method (MSD) using H_2S gas source was proposed to overcome problems caused by using sulfur source. Crystallinity and composition of SrS:CeCl_3 phosphor film prepared by this technique was analyzed. Deposited films was confirmed to have the (200) preferential orientation and to be stoichiometry. Characteristics of electroluminescent (EL) devices with phosphors prepared by MSD using H_2S and effects of insulating materials were investigated. EL devices with SiAlON films as first insulating layers were confirmed to have high luminance, which probably resulted from the smaller change of dielectric loss of SiAlON to the heat treatment compared to the other dielectric materials.
