Abstract

Luminescence properties of Pr³⁺ and Dy³⁺ doped GaGeSbSe(S) vitreous systems have been studied. The synthesis process to obtain homogeneous glasses has been determined and fibers have been successfully drawn from the produced preforms and characterized. Fibers show a mid-IR luminescence matching with the CO₂ absorption band at 4.3 μm and can be used in an environmental monitoring sensor for the CO₂ underground storage. The luminescence and glasses properties have been investigated on bulk samples and fibers in order to improve the efficiency of an optical CO₂ sensor prototype operating from high to low concentration, down to the ppm level.
