Abstract

ABSTRACT Chalcogenide glass-formers are being used in a remarkable range of various optoelectronic, photonics, photoconducting, sensing and memory device applications. The knowledge of viscosity is essential for the processing of any glass-forming material, in particular for the fabrication of precise optical elements, which is the main application field of chalcogenide glasses. This work presents an extensive collection of all available viscosity data for chalcogenides, including the measurement methods. The Mauro–Yue–Ellison–Gupta–Allan (MYEGA), Arrhenius and VFT equations are used to fit the temperature dependences of viscosity. The viscosity glass transition temperatures, fragilities and apparent activation energies are calculated from these fits. Consequently, these parameters are discussed with regard to the compositional evolution of the respective chalcogenide systems.

硫族化合物玻璃形成剂的粘度

摘要硫系玻璃形成剂被广泛应用于各种光电子、光子学、光电导、传感和存储器件。粘度的知识对于任何玻璃形成材料的加工都是必不可少的，特别是对于精密光学元件的制造，这是硫族化物玻璃的主要应用领域。这项工作广泛收集了硫族化物的所有可用粘度数据，包括测量方法。Mauro–Yue–Ellison–Gupta–Allan（MYEGA）、Arrhenius和VFT方程用于拟合粘度的温度依赖性。根据这些拟合计算了粘度-玻璃化转变温度、脆性和表观活化能。因此，关于各个硫族化物系统的组成演变来讨论这些参数。
