SITE-SELECTIVE LUMINESCENCE OF SOLID SOLUTIONS BASED ON SILICATE-TUNGSTATES DOPED WITH Eu3+ IONS

Energy transfer processes and europium-ion spectroscopic manifestations in Ca2La6.8Eu1.2Si5.6W0.4O26.4 and Ca8Eu2Si3W3O26 solid solutions were studied using photolu-minescence spectroscopy and upon X-ray excitation.The work was partially supported by the Ministry of Science and Higher Education of the Russian Federation (through the basic part of the government mandate, project No. FEUZ-2020-0060) and RFBR (project No. 20-03-00851)
