Abstract

The near-IR emission spectra of Er3+Tm3+ codoped 70GeS220In2S310CsI chalcohalide glasses were studied with an 808nm laser as an excitation source. A broad emission extending from 1.35to1.7μm with a FWHM of 160nm was recorded in a 0.1mol.% Er2S3, 0.5mol.% Tm2S3 codoped chalcohalide glass. The fluorescence decay curves of glasses were measured by monitoring the emissions of Tm3+ at 1460nm and Er3+ at 1540nm, and the lifetimes were obtained from the first-order exponential fit. The luminescence mechanism and the possible energy-transfer processes are discussed with respect to the energy-level diagram of Er3+ and Tm3+ ions.
