The pa.er dea.t with the study of fluorescence properties of sol-gel systems doped with ra.e-ea.th ions a.d co-doped with silv.r. The genera. problem for these types of inorga.ic phosphors wa. a.v.ry low a.sorba.ce in the v.sible ra.ge. Therefore, a.sensitizer of luminescence of the ra.e-ea.th ions should be selected a.d used. The sensitizer should possess a.good a.sorba.ce in the v.sible ra.ge a.d strong intera.tion with the ra.e-ea.th ions. In this study silv.r ions were selected a. the sensitizer.
