采用太赫兹时域光谱技术对硫系玻璃进行了研究。特别是，在太赫兹频率的介电性能进行了测定，并与玻璃组合物。实验结果表明，玻璃的介电性能和极化率之间有很强的关系。提出了一种新的解释的基础上的金属阳离子的配位数来理解这些意见。(C)2017作者由爱思唯尔公司出版
Terahertz time-domain spectroscopy (THz TDS) was used to investigate a series of chalcogenide glasses. In particular, the dielectric properties at terahertz frequencies were determined and correlated with the glass composition. The experimental results showed a strong relationship between the dielectric properties and the polarizability of the glasses studied. A new explanation based on the coordination number of the metallic cations was proposed to understand these observations. (C) 2017 The Authors. Published by Elsevier B.V.
