Determinação dos parâmetros ópticos, estruturais e espectroscópicos de vidros fosfato-silicato dopados com Érbio: parâmetros Judd-Ofelt

Abstract

Glasses Phosphates are technologically important materials due to their physical and chemical properties and can be applied to optical systems , through the doping with rare earth ions . In this work, the production by the technique of melting / cooling and characterization of silicon phosphate glasses doped with trioxide erbium 𝐸𝑟2𝑂3, to verify the influence of dopants when added to the host matrix. The use of termal, optical and structural the characterization techniques: Density, Linear Refractive Index (RLI), Absorption Optics (AO), photoluminescence steady state (FL) and photoluminescence Time-Resolved (FLTR ); with and Judd - Ofelt calculations it was possible to map out promising characteristics of these glasses for technological applications , especially in data transmission by optical fibers, use in telecommunications.
