ABSTRACT = {We investigated the effect of the elemental substitution of As by Sb on the threshold 
behaviours in Ge<sub>x</sub>Sb<sub>10</sub>Se<sub>90-x</sub> glasses. We found that, while the transition thresholds at 
MCN=2.4 and 2.67 were verified in the GeAsSe glasses, the transition thresholds can be 
changed to chemically stoichiometric compositions if As is substituted by Sb. We further 
deconvolved Raman spectra into different structural units and the change of their 
respective intensity showed the same behaviour, and this was ascribed to the chemical 
effect induced by a large difference of the atomic radius between As and Sb, and a 
relatively strong ionic feature of the element Sb. },
