The viscosity of Ge10As40Se50 chalcogenide glass was investigated by fiber elongation and rotation methods. The Vogel-Fulcher-Tammann equation was proposed as an optimal fitting model after comparing to the accuracy of different equations. GexAsySe1-x-y glasses were compared according to the fragility, m, derived from the Angell plot. The network structure of Ge10As40Se50 chalcogenide glass was investigated by X-ray photoelectron spectroscopy (XPS). The results show that the fragility change of GexAsySe1-x-y glasses follows the topological constraint theory in the range of the average coordination numbers (i.e., r=2.0-2.6). The m of GexAsySe1-x-y glasses decreases as r increases. However, the m does not strictly decrease as r increases when r is greater than 2.2. Based on the XPS results, Ge10As40Se50 chalcogenide glass exists Se chain in the network structure, thus affecting the stability and results at a greater m.
