Chalcogenide glasses are defined as a new category of non-crystalline solids on the basis
of their characteristic covalent bonds and unique properties, such as broad infrared …

The progress, and current challenges, in fabricating rare-earth-doped chalcogenide-glass
fibers for develo** mid-infrared (IR) fiber lasers are reviewed. For the first time a coherent …

Optical gain materials activated by dopants are playing pivotal roles in fiber amplifiers, solid-
state lasers and biological imaging. Achieving high photoluminescence (PL) efficiency in a …

The spatial distribution of Nd 3+ ions and GaS 4 tetrahedral units in Nd-doped Ge-As-Ga-S
glasses has been studied by laser spectroscopy and ab initio molecular dynamics (MD) …

The distribution of Tm 3+ and Ni 2+ ions is unambiguously exhibited in 80GeS 2-20Ga 2 S 3
chalcogenide glass ceramics (GCs) containing Ga 2 S 3 nanocrystals (NCs) by using …

We report on the optical and magnetic properties of Tm_2O_3-doped calcium
aluminosilicate glasses with dopant concentrations of up to 7 mol%. These materials provide …

A systematic investigation is presented, for the first time, of a 1000 ppmw (parts per million,
by weight) Dy3+‐doped Ge–As–Ga–Se chalcogenide glass series, with a fixed low Ga …

Gallium (Ga) helps solubilize rare‐earth ions in chalcogenide glasses, but has been found
to form the dominant crystallizing selenide phase in bulk glass in our previous work. Here …

Abstract The Ge 20 Ga 5 Sb 10 S 65 glasses doped with Er 3+ ions (0; 0.1; 0.5; 1.0 mol.%)
are investigated with optical, fluorescence and positron annihilation lifetime (PAL) …

In this work, we reported the fabrications and characterization of Er 3+-doped Ge 20 Ga 5 Sb
10 Se 65 glasses and glass-ceramics and measured their transmission and fluorescence …
