“…It was decreased from 64.48 μs of Dy-doped sample to 60.05μs of Ni/Dy codoped sample. The lifetimes of Dy-doped and Ni/Dy codoped glasses were larger than that was measured in Ge-As-S glass (29μs, [14]). …”

The infrared emission properties of rare-earth (i.e., Dy 3+ , Pr 3+ or Sm 3+ ) and nickel-codoped Ge-Ga-Sb-S glasses were investigated by photoluminescence measurements. It was found that the emission intensities of the rare-earth doped glasses were significantly weakened even with very few amount of nickel (i.e., 500 atomic ppm). On the other hand, the nickel doped glasses show larger indices of refraction, which property will be desirable in nonlinear optics. Our results, however, suggest that to obtain rare-earth doped chalcogenide glasses of better infrared emission property it is necessary to keep the nickel dopant as low as possible.

“…1 are non-exponential to some extent especially for a long elapsed time. Energy transfers among Dy 3+ ions are known to be responsible for this behavior [21]. In short, a population feeding to the ( 6 F 11/2 , 6 H 9/2 ) level can happen even after the cease of the optical excitation via the cooperative upconversion energy transfers associated with the lower-lying levels with longer population duration times.…”

“…Starting materials of elemental Ge, Sb (Advanced Materials) and Se (Alfa Aesar) were all better than 99.999% in purity. Synthesis of glass specimen was carried out following the conventional processing technique for chalcogenide glass [8][9][10]. Each silica ampoule containing desired composition was kept for 12 hours at 1200…”

Chalcogenide glass in the ternary Ge-Sb-Se system is inherently moldable, thus being considered as a strong candidate material for use in infrared-transmitting lens applications from the viewpoint of thermal and mechanical stability. In an effort to experimentally determine compositional region suitable for the molded lens applications, we evaluate its compositional dependence of hardness. Among the constituent atoms, Ge content turns out to exert a most conspicuous correlation with hardness. This phenomenological behavior is then explained in connection with the structural evolution that Ge brings about.
