Porous glass to which molecules of organic dyes have been added is a promising active solid medium for tunable lasers. The spectroluminescent characteristics of samples of porous glass activated with rhodamine 6G molecules have been studied. It is shown that molecules of rhodamine 6G adsorbed in porus glass retain their capacity for fluorescence with a high quantum yield. Fixation of rhodamine 6G molecules on the pore walls interferes with their association in the concentration range up to 10/sup 19/ cm/sup -3/. Concentration quenching of fluorescence is observed starting with a concentration of dye molecules of 5 x 10/sup 15/ cm/sup -3/; this is explained by inductive-resonance energy transfer between monomeric molecules under conditions of inhomogeneous broadening of the electronic spectra of the adsorbed molecules.
