Description
An increasing interest in investigations of chalcogenide glasses has been observed in recent years. This interest is due to their specific properties and to the possibilities for their applications in different fields of science. The optical devices, on the basis of the photo-induced phase transition between amorphous and crystalline states in chalcogenide glasses, are possible candidates for the micro- and nano-electronics. Here, we analyzed the basic physical properties of samples of Ge-As-Se and As-Se chalcogenide glasses for planning a of chalcogenide aspheric lens. Differentiated differential thermal analysis/thermogravimetry (differentiated DTA/TG) revealed that the activation energies of the crystallizations of Ge10As40Se50 and As40Se60 were approximately 3.6 eV and 3.3 eV, respectively.
