Dy3+‐Doped Selenide Chalcogenide Glasses: Influence of Dy3+ Dopant‐Additive and Containment
TL;DR: In this article, the effect of contamination from the silica glass ampoule containment used in chalcogenide glass synthesis is studied, showing that Dy-foil is better than DyCl3 as the Dy3+ additive in Ge-As-Ga-Se glass in aspects of avoiding bulk crystallization, improving glass surface quality and lowering optical loss.

Optical Constants of Water in the 200-nm to 200-microm Wavelength Region.
George M. Hale,Marvin R. Querry +1 more
TL;DR: Extinction coefficients k(lambda) for water at 25 degrees C were determined through a broad spectral region by manually smoothing a point by point graph of k( lambda) vs wavelength lambda that was plotted for data obtained from a review of the scientific literature on the optical constants of water.
