Abstract:CP 6154-13081-970-Campinas-SP Recebido em 2/12/96; aceito em 7/7/97 OPTICAL PROPERTIES STUDY IN 0.3La 2 S 3-0.7Ga 2 S 3. In this work we describe the synthesis and characterization of chalcogenide glass (0.3La 2 S 3-0.7Ga 2 S 3) with low phonons frequencies. Several properties were measured like Sellmeier parameters, linear refractive index dispersion and material dispersion. Samples with the composition above were doped with Dy 2 S 3. The absorption and emission characteristics were measured by electronic spe… Show more
