Abstract

The processes of glass-transition and crystallization of chalcogenide glass As40Se30Te30 with 5 at.% silver were analyzed using differential scanning calorimetry. The values of glass-transition temperatures and activation energy were determined. Two crystallization processes were also detected and three-dimensional growth. Using non-isoconversional models the activation energies for both processes amounted to 112(2) kJ/mol and 97(2) kJ/mol. Isoconversional models were used to track changes in activation energy. The presence of Te significantly affects the thermal parameters as well as the structure of the glass while the presence of Ag does not significantly change the degree of connectivity of the As40Se30Te30 glass matrix.

掺银 As40Se30Te30 卤化物玻璃中的热诱导过程动力学

使用差示扫描量热仪分析了含 5%银的铬化玻璃 As40Se30Te30 的玻璃跃迁和结晶过程。测定了玻璃跃迁温度和活化能的值。此外，还检测了两个结晶过程和三维生长过程。使用非等转换模型，两个过程的活化能分别为 112(2) kJ/mol 和 97(2) kJ/mol。等转换模型用于跟踪活化能的变化。Te 的存在对热参数和玻璃的结构有很大影响，而 Ag 的存在并没有明显改变 As40Se30Te30 玻璃基体的连接程度。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
