Gallium-sodium-sulfide glasses have been shown to be the most promising host for the 1.3um fibre 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% Ga203 was introduced into the melts. Both bulk crystallization and surface crystallization can take place in this system.
