Nd3+: Ga-Ge-Sb-S glasses and fibers for luminescence in mid-IR: synthesis, structural characterization and rare earth spectroscopy

Popis výsledku v původním jazyce

The glass transition temperature, density, expansion coefficient, and near and mid-IR refractive indexes were measured on bulk Ga-Ge-Sb-S glass samples. Their glass network structures were analyzed by Raman scattering spectrometry, NMR of Ga-71 and EXAFS, K-edge of Ga, Ge, Sb, S and Nd. The absorption and emission spectra of neodymium doped sulfide glasses were recorded from the visible to the mid-IR. Excited state lifetimes were measured for several transitions. The lifetimes decrease with the concentration of Nd3+, especially for the 4I13/2 and 4I11/2 levels. The spectroscopic parameters were determined by the Judd-Ofelt method, allowing the calculation of cross-section emissions and the evaluation of quantum yields. Optical attenuation and emission measurements of fiber were also performed with a broad 4.7-5.7 mu m emission band in the mid-IR.
