摘要:

采用熔融淬冷法制备了系列Ge3Se5Te2Snx(x=0、0.4、0.8、1.2、1.6、2.0, mol%)硫系玻璃。采用X射线衍射(XRD)图谱、差示扫描量热曲线(DSC)、可见/近红外光谱、傅里叶红外(FTIR)光谱、显微拉曼光谱等手段对玻璃的物化性能及结构进行表征, 研究发现Sn的引入导致Ge-Se-Te玻璃系统物化性能的变化: 玻璃的转变温度Tg降低、红外截止波长发生红移, 并有效地降低了杂质吸收峰对样品红外透过率的影响。利用Philips网络约束理论计算的玻璃平均配位数及拉曼光谱的变化, 讨论了引入Sn对Ge-Se-Te玻璃的影响。

Abstract:

A series of Ge3Se5Te2Snx(x=0, 0.4, 0.8, 1.2, 1.6, 2.0, mol%) chalcogenide glasses were prepared by traditional melt-quenching method. The physiochemical properties and structure changes of glasses were characterized by employing the techniques of X-ray diffraction (XRD), differential scanning calorimetry (DSC), visible-near IR spectrum, Fourier transform infrared spectrum (FTIR), and Raman spectroscope. Physiochemical properties of Ge-Se-Te glasses change with the addition of Sn, including glass transition temperature (Tg) decreacing and infrared cut-off wavelength shifting toward long wavelength which effectively inhibits the absorption peaks of impurities in the mid-IR spectral region. In addition, the origination behind these phenomena is discussed by the average coordination number calculated from Philips network-constrained theory and structural evolution of Raman spectra.

Key words: chalcogenide glasses, thermal stability, infrared spectroscopy
