Journal ArticleDOI
Chalcohalide glasses for infrared fiber optics
TL;DR: In this article, the properties and structure of various glass-forming chalcohalide systems were reviewed, showing that the packing density, glass transition temperature, and refractive indices decrease with the addition of a halogen component into binary chalcogenide glasses.
Journal ArticleDOI
Chemical characteristics of Dy-S bonds in Ge-As-S glass
TL;DR: From Dy L 3 -edge extended X-ray absorption fine structure spectroscopic analysis of Dy-doped Ge-As-S glass, this article verified that both the coordination number and Dy-S distance are decreased in this representative chalcogenide glass compared to those in the Dy 2 S 3 crystalline counterpart.
Journal ArticleDOI
Direct Imaging of the Distribution of Nd3+ Ions in Glasses Containing PbS Quantum Dots
Won Ji Park,Chao Liu,Jong Heo +2 more
TL;DR: In this article, the influence of Nd3+ ions on the precipitation and optical properties of PbS quantum dots inside silicate glasses was investigated, and it was shown that Nd−O clusters are preserved during heat treatment and serve as nucleation sites for Pb-S crystals.
Journal ArticleDOI
Infrared emission from Er3+/Y3+ co-doped oxyfluoride glass-ceramics
Zhiyong Zhao,Chao Liu,Yang Jiang,Jihong Zhang,Haizheng Tao,Jianjun Han,Xiujian Zhao,Jong Heo,Jong Heo +8 more
TL;DR: In this article, the authors investigated the infrared emission properties of oxyfluoride glasses with nominal compositions of 55SiO 2 -10Al 2 O 3 -(35−−x−−y)PbF 2 -xErF 3 -yYF 3 (in mol%) with x ǫ = 0.1, 0.2, 0.3, or 0.5 and yǫ= 0 or 1.0, were investigated.
Journal ArticleDOI
Energy transfer and 1.48 μm emission properties in chalcohalide glasses doped with Tm3+and Tb3+
Dong Jun Lee,Jong Heo,Se Ho Park +2 more
TL;DR: In this paper, the authors evaluated the performance of chalcohalide glasses doped with Tm 3+ and Tb 3+ for S-band fiber-optic amplifiers.
