【摘要】：硫系玻璃同目前常用的其他红外材料相比,具有红外波段透过谱宽、可模压成型、非线性效应强、力学性能好、化学性质稳定和玻璃性能随玻璃组分改变可调等特点,在科学研究、工业、医学和国防等领域具有重要的应用价值。基于硫系玻璃的硫卤多光谱玻璃,结合了硫系玻璃和卤化物玻璃的特点,拓宽了硫系玻璃在可见光波段的透过光谱范围。本文在已报道硫系玻璃和硫卤玻璃的研究基础之上,对硫卤玻璃的组成进行了优化研究,提出了一种新的调节玻璃性能的方法,并制备出了与玻璃组成相对应的玻璃样品。鉴于制得的玻璃样品的红外透过谱上存在较强的杂质吸收峰,设计出了相应的提纯方案,明显降低了杂质吸收峰的强度。优化了玻璃的制备工艺参数,掌握了φ30mm口径玻璃的制备工艺。最后对玻璃样品进行微晶化处理,研究了晶化处理对玻璃性能的影响。绪论部分对本文的选题背景和意义进行了阐述,介绍了多光谱材料的定义、应用、种类和优缺点、国内外的研究进展等。简要介绍了多光谱玻璃的硫系玻璃基质和硫卤玻璃基质,并提出了本文的研究思路和内容。第二章对本文的实验方法和理论基础进行了介绍。第三章研究了双卤化物共掺新型硫系多光谱玻璃的制备及性能,为调节硫卤玻璃性能提供了一种新的方法。第四章阐述了对硫卤玻璃的提纯工艺的改进方法以及明显的效果。第五章探索了大口径硫卤多光谱玻璃的制备工艺,并成功制备出口径为φ30mm的较大口径硫系多光谱玻璃。第六章研究了晶化处理对玻璃性能的影响。第七章总结了本文的工作内容,并指出了存在的不足以及所需的改进。
[Abstract]:Chalcogenide glass compared with other commonly used infrared materials, with infrared transmission spectrum, can be molded, strong nonlinear effects, good mechanical properties, stable chemical properties and performance of glass with glass components change characteristics of adjustable, industry in scientific research, and has important application value in the field of medicine and national defense. Chalcohalide chalcogenide glass glass based on multi spectrum, combined with the characteristics of chalcogenide glass and glass halide, broaden the chalcogenide glass in the visible band through the spectral range. Based on the research of chalcogenide glass has been reported and chalcohalide, composition of chalcohalide glass was studied, put forward a new method of adjusting the properties of glass, and prepared with glass composition corresponding to the glass samples. In view of the prepared glass samples of the infrared transmission spectrum has strong absorption peaks of impurities, designed corresponding The purification scheme significantly reduces the impurity absorption peak intensity. The optimization of glass preparation parameters, mastered the preparation process of 30mm caliber glass. At the end of the glass sample was crystallized., studied the effect of heat treatment on the properties of glass. The introduction part of the background and significance of this paper are described introduces the definition, multi spectral, material application, types and advantages and disadvantages, research progress at home and abroad. It briefly introduces the chalcogenide glass matrix and chalcohalide glass matrix spectra of glass, and put forward the research ideas and contents. The second chapter introduces the experimental methods in this paper and the theoretical basis. The third chapter studies the preparation and properties of Co doped double halide chalcogenide glass multi spectral model, provides a new method for regulating chalcohalide glass properties. The fourth chapter describes the purification process of chalcohalide glass modification Method and obvious effect. The fifth chapter explores the preparation process of large caliber chalcohalide glass multi spectral, and successfully prepared the export size of large caliber chalcogenide 30mm diameter multi spectral glass. The sixth chapter studies the effects of heat treatment on the properties of glass. The seventh chapter summarizes the content of the work, and points out that the shortcomings and improvement is needed.
