中文摘要	a new composition content quaternary-alloy-based phase change thin film, sb-rich aginsbte, has been prepared by dc-magnetron sputtering on a k9 glass substrate. after the film has been subsequently annealed at 200degreesc for 30 min, it becomes a crystalline thin film. the diffraction peak of antimony (sb) are observed by shallow (0.5 degree) x-ray diffraction in the quaternary alloy thin film. the analyses of the measurement from differential scanning calorimetry (dsc) show that the crystallization temperature of the phase change thin film is about 190degreesc and increases with the heating rate. by kissinger plot, the activation energy for crystallization is determined to be 3.05ev. the reflectivity, refractive index and extinction coefficient of the crystalline and amorphous phase change thin films are presented. the optical absorption coefficient of the phase change thin films as a function of photon energy is obtained from the extinction coefficient. the optical band gaps of the amorphous and crystallization phase change thin films are 0.265ev and 1.127ev, respectively.
