【摘要】 报道了BiCl₃-KCl-As₂S₃系玻璃的形成。以BiCl₃和As₂S₃为基础的玻璃的红外透过率直到11μm以后才开始下降,这对CO₂激光（10.6μm）传输非常有利。在BiCl₃-KCl系中引入As₂S₃可显著改善玻璃的化学稳定性。根据喇曼光谱结果,分别研究了BiCl₃-KCl系全氯化物玻璃及BiCl₃-KCl-As₂S₃混合系玻璃的结构。更多还原

【Abstract】 The glass forming region in the ternary system of BiCl₃-KCl-As₂S₃ is identified. The IR transmittance of the glasses based on BiCl₃ and As₂S₃ does not decrease until the wavelength of 11μm, therefore, these glasses are proper for the transmission of CO₂ laser. The chemical durability of the BiCl₃-KCl system glasses is increased by the introduction of As₂S₃. The structure of BiCl₃-KCl system chloride glasses and the glasses based on the mixed system of BiCl₃-KCl-As₂S₃ is studied by Raman spectra.更多还原
