| Abstract: | Tb3+-doped oxysujiides of lanthanum, yttrium and gadolium are good luminophors. In order to find efficient materials, scme Tb-cloped solid solutions of rare earth oxysulfides were investigated. (Y1-xLax)2O2S:Tb, (Gd1-x Lax)2O2S:Tb and (Y1-xLax)2O2S:Tb were prepared by high temperature sulfidization of the relevant rare earth cxices mixtuies. Their emission properties under the X-ray excitation were celermined and discussed.Four compositions have been selected from them and Were ccnsicered as candidates for luminophors used in X-rays intensifying screens. |
