Research on structure and mid-infrared photoluminescence of Ga3+/Er3+ co-doped As-S glasses
Source abstract
Abstract
Abstract In this study, a series of Ga-As-S glasses tailored by adding Ga as the host for Er 3 + ions were prepared and characterized. The effects of the introduction of Ga on the structure change and the Er 3 + middle infrared emission intensity have been studied by Raman scattering, X-ray diffraction and fluorescence spectra. The results show the incorporating of Ga into the As 2 S 3 glass induced the dissociation of [AsS 3/2 ] pyramids units in behalf of forming tetrahedral [GaS 4/2 ]. By adjusting the Ga content, this host can be doped up to 2 mol% Er 3 + without crystallization and concentration quenching effect. Besides, this system has very good thermal stability (ΔT > 230 °C) and strong broadband mid-infrared emission centered at 4700 nm, suggests that this system has the potential to be used as mid-infrared fiber material.
