Abstract

Absorption and fluorescence spectra and lasing ability of pyran derivatives in thin polymeric layers (0.5–0.8 μm) based on polymethylmethacrylate and copolymerized methylmethacrylate and methacrylic acid are investigated. It is revealed that the absorption and luminescence intensities and the laser service lifetime of dicyanomethilene (DCM) pyran derivatives are determined by their composition and nature of the polymeric medium. Compositions based on DCM and examined polymers are of interest for preparation of thin-film active media lasing in the red range of the spectrum.
