Solid-state active elements based on poly(urethane-
co
-siloxanes) with the organic dye rhodamine 6G in their pores are studied. The transparency range of polymer samples is determined. The electronic spectra and the spectra of luminescence and lasing of rhodamine 6G in poly(urethane-
co
-siloxane) samples are measured. When a polymer obtained at a high content of 2,4-toluene diisocyanate is doped with rhodamine 6G, the luminescence spectrum narrows by a factor of 10. It is shown that the polymers doped with rhodamine 6G feature high photostability. The photostability of rhodamine 6G molecules is strongly dependent on the content of the dimethylsiloxane component in the polymer.
