The development of new materials for different optical applications is one of the most important topics for the photonics industry. In the present work we study the optical properties of a new photonics medium consisted of an epoxy based polymer as matrix with dissolved binary solutions of Rhodamine 6G and Rhodamine B. Detailed study of the spectral dependence of fluorescence of the new medium has been performed. It was found that the intensive fluorescence follows the spectral dependence of dyes’ transmission in spectral interval 390 – 780 nm. The new medium’s fluorescence was studied by means of spectrofluorimeter FluoroLog 3-22. The stimulated emission was obtained with irradiation by SHG Nd:YAG laser with parameters: energy – 50 – 100 mJ, wavelength – 532 nm, repetition rate 1 Hz and pulse duration of 10 ns and measurement by high-resolution nanosecond Michelle 5000 spectrograph (ICCD detector). Studies have shown that stimulated radiation is characterized by very narrow lines of radiation throughout the fluorescence spectral range. The medium can be made with different rigidity depending on the concentration of different solvents. It is remarkable that in a wide range of solvents and dyes concentration the medium properties are determined by mixture as a whole. The relationship between the optical properties of this new material and its nanostructured morphology is shown. Due to the large tolerance of rigidity the material can be made in different forms and dimensions, as well bulk medium, optical active fibers and thin films. [ABSTRACT FROM AUTHOR]
