摘要

Tm 3+ -doped GeS2-In2S3-CsBr chalcohalide glasses are presented and their infrared luminescence properties at S-band are investigated. Composition of glass matrix is 70GeS2-10In2S3-20CsBr (mol %) with the concentration of Tm2S3 in the range of 0.05-1.00 (mol %). The results showed that the optimal Tm2S3 doping concentration was 0.25 mol % at which the glass exhibited an enhanced emission peaking at 1480 nm with a full width at half maximum (FWHM) over 100 nm.
