Effects of Oxide Content on the Glass-Forming Ability of the Ga2S3-Na2S System

Gallium–sodium–sulfide glasses have been shown to be the most promising host for the 1.3 μm fiber optic amplifier so far. However, the current study has revealed that the formation of stable glasses in this system relies on the existence of a certain amount of oxide in the composition. A glass‐formi...

Description
Summary:Gallium–sodium–sulfide glasses have been shown to be the most promising host for the 1.3 μm fiber optic amplifier so far. However, the current study has revealed that the formation of stable glasses in this system relies on the existence of a certain amount of oxide in the composition. A glass‐forming region was identified when 3 mol% Ga2O3 was introduced into the melts. Both bulk crystallization and surface crystallization can take place in this system. The thermal behavior of the glasses obtained was studied by DTA and characteristic infrared and UV/visible transmission spectra are presented. The current results are discussed and compared with those previously reported.
