Transition metal-doped chalcogenide glasses for broadband near-infrared sources
In this paper we report the spectroscopic data for samples of 0.031% iron, 0.017% nickel, 0.01% chromium and 0.017% cobalt (molar) doped gallium lanthanum sulphide (GLS) glass. Photoluminescence (PL) with a full width half maximum (FWHM) of around 500 nm and peaking between 1120 nm and 1460 nm is observed when excited using wavelengths of 850 nm and 1064 nm. The emission lifetime for nickel-dop...

متن کاملGeS2–In2S3–CsI Chalcogenide Glasses Doped with Rare Earth Ions for Near- and Mid-IR Luminescence
Chalcogenide glass has been considered as a promising host for the potential laser gain and amplifier media operating in near- and mid-IR spectral region. In this work, the IR luminescence spectra of rare earth ions (Tm3+, Er3+, and Dy3+) doped 65GeS2-25In2S3-10CsI chalcogenide glasses were measured under the excitation of an 808 nm laser diode. To the best of our knowledge, it firstly provides...
متن کاملShort and Medium Range Order in Se1-xTex Glasses
Complementary XAFS measurements (LURE and NSLS) of Sel,Te, glasses have been canied out on both the Se and Te Kedges at low and room temperatures. Using a multi-shell best fit analysis procedure, we have reconstructed the Se and Te local environment: (i)first shell intrachain nearest neighbors (Se-Sel, Se-Tel, Te-Se~,and Te-Tel); (ii) second shell intrachain (Se-Sez and Se-Tez) and interchain n...
متن کاملPhotoinduced Fluidity and Viscoelasticity in Chalcogenide Glasses
This work is an attempt to apply conventional mechanical testing to characterize the photoinduced viscoelastic behavior of chalcogenide glasses. Creep or relaxation-recovery experiments are usually performed to characterize the delayed elastic contribution to deformation, during thermally activated flow. In this paper, relaxation-recovery is used to characterize delayed elasticity under irradia...
