| 摘 要： | 用熔融淬冷法制备了一系列Ge-Te-Ag硫系玻璃,并确定了玻璃态的成玻区。通过阿基米德排水法、X射线衍射(XRD)、差示扫描量热(DSC)、可见/近红外吸收(UV-VIS-NIR)光谱和傅里叶红外透射(FTIR)光谱等技术,研究了玻璃态的物理特性、热学特性以及光学特性。研究表明,玻璃态的密度随着Ag含量的增加而增大;Ag的掺入改善了玻璃态的形成能力和热稳定性;随着Ag含量的增加,玻璃态的短波吸收限发生了红移,而红外截止波长基本没变化;玻璃态有着较宽的红外透过范围(1.8～20.0μm),表明其在远红外领域具有很大的应用前景。

| Abstract: | A series of Ge-Te-Ag chalcogenide glasses were prepared by traditional melt-quenching method and the glass-forming region was determined.Archimides principle,X-ray diffraction(XRD),differential scanning calorimetry(DSC),ultra violet-visible-near infrared(UV-VIS-NIR) absorbtion spectrum,Fourier transform infrared spectrum(FTIR) were adopted to analyze physical,thermal and optical properties of sample glasses.The results show that the density of glasses increases with the increase of Ag.The glass forming ability and the thermostablity of the glasses are improved when Ag is doped in.In addition,a red-shift occurs at the short-wavelength absorbtion cutoff edge while the infrared cutoff wavelength is nearly unchanged with the increasing of Ag.The wide infrared transmission of this glass system reveals that it may have great potential application in far-infrared material fields. |
