Chalcohalide glasses 20GeSe2-（80-x）Sb2Se3-xCsCl（x＝2，4，8，10 mol%）were synthesized by the conventional melt-quenching method. The optical transmission spectra were measured from the visible to the far-infrared range. The effect of CsCl content on the short-edged wavelength was investigated. Moreover，the differential thermal analysis curves of a typical 20GeSe2-76Sb2Se3-4CsCl glass were measured under different heating rates，and its crystallization kinetics was analyzed under the non-isothermal condition. The results show that，the introduction of CsCl into the glass lowers the non-bonding energy level，which leads to the increase of the electronic bandgap Eg，and blue-shift of the short edged wavelength. Compared with the conventional Johnson-Mehl-Avrami model，the autocatalytic model gives a better description of the kinetic process for the glass sample.
