Abstract
The absorption and fluorescence spectra and the lasing ability of aminocoumarin derivatives in thin polymer layers (0.5–0.8 µm) based on the copolymer methylmethacrylate with a methacrylic acid and the copolymer methylmethacrylate with glycidylmethacrylate formed by coating of optically transparent glass substrates have been studied. It is found that the intensity of absorption and luminescence as well as the lasing resource of coumarins are determined by the structure of the latter and by the nature of the polymer medium. Compositions based on the copolymer methylmethacrylate with glycidylmethacrylate and aminocoumarin derivatives with a fluorized methyl group at the 4th molecular position can be of interest in optical technologies (light transformers, amplifiers).
