Study of crystallization kinetics and structural relaxation behavior in phase separated Ag33Ge17Se50 glassy alloys

► Phase separation in Ag33Ge17Se50 glassy alloy bordering two glass forming regions. ► Transformation of Ag8GeSe6 → Ag2Se along with crystallization GeSe2 phase. ► Elucidation of various kinetic parameters for the crystalline transformation. ► Structural relaxation in thermally evaporated films by optical spectroscopy.
