Bulk glasses of the Ge5Se25Te70 system were prepared by the conventional melt-quenching technique. Thin films with a thickness of 150 nm of Ge5Se25Te70 were prepared by the thermal evaporation technique on glass substrates. The crystallization mechanism has been studied by using differential scanning calorimeter (DSC) technique. The effect of heat treatment on the structure transformation was investigated by X-ray diffraction and the scanning electron microscope. The effect of heat treatment on the optical properties was also investigated. (c) 2006 Elsevier B.V. All rights reserved.
