Abstract
En 中文
Tellurite-tungsten glasses doped with Er3+-Pr3+ were fabricated by conventional melt-quenching, increasing the Pr2O3 content to enhance the emission performance and bandwidth of the 1.5 mu m emission band. The spectroscopic properties in the visible and near-infrared regions are described, besides the Judd - Ofelt analysis of the Er3+. Results of the 1.5 mu m emission intensity of the Er3+ under 980 nm, moreover the up-conversion emission, show an enhancement with the addition of Pr3+. Increments in the FWHM (approximate to 90 nm) in the Er3+: 4I13/2 -> 4I15/2 band are also reported, where the increment of Pr2O3 content plays an important role. The analyses of the dynamics between Er3+ and Pr3+ in these glasses comprehensively explain the Er3+ emission performance in the visible and near-infrared regions for optical communications applications.
