【摘要】：近年來,紅外(IR)技術(shù)在國防、空間技術(shù)以及經(jīng)濟現(xiàn)代化建設發(fā)揮的重要作用日益突出。隨著紅外市場的強勁增長和新的應用領域持續(xù)開拓,對透可見至紅外的多光譜材料的需求也日益增長。硫鹵玻璃作為多光譜材料不只在紅外波段擁有較寬的透過范圍,同時還可延伸至部分可見光波段,其性能隨組分可調(diào)、寬的透過光譜并且成本低廉等特點而倍受廣大科研工作者和應用廠家的關注。本文結(jié)合前人所做的一些工作總結(jié),制備了一系列Ge-In(Ga)-Se-CsBr、GeGa-In-Se-CsBr、Ge-Ga-Se-RbBr系統(tǒng)硫鹵玻璃,使用儀器測試與數(shù)值計算曲線擬合等輔助手段對樣品的物理性能、熱穩(wěn)定性和光學性能進行研究和討論。選用性能良好的60GeSe_2-25Ga_2Se_3-15CsBr組分作為大尺寸玻璃樣品的制備,尋找性能優(yōu)良且低成本的多光譜玻璃材料。論文的第一章為緒論部分,首先簡要概述了多光譜玻璃材料和硫系玻璃,介紹了它們的發(fā)展歷程和研究現(xiàn)狀,進而提出本工作研究的內(nèi)容、方法、目的及意義。第二章主要對Se基多光譜硫系玻璃中的幾種常見性能,如成玻特性、光學性能等進行了簡要的介紹。同時,對性能參數(shù)計算的理論基礎等進行簡要的回顧。第三章主要介紹了Se基多光譜硫系(鹵)玻璃的研究方法,包括傳統(tǒng)的硫系玻璃制備工藝流程及玻璃樣品的各項性能測試,主要包括物理、熱學及光學性能。第四章為多光譜硫系玻璃材料組分探索及優(yōu)化研究,首先分別針對Ge-InSe-CsBr和Ge-Ga-In-Se-CsBr兩組分的性能研究和分析。結(jié)果表明,摻Ga元素玻璃不僅在成本而且在性能上包括物理特性、熱穩(wěn)定性及光學特性均具有優(yōu)勢。因此,選取Ge-Ga-Se玻璃系統(tǒng)來制備大尺寸(直徑φ30及以上)多光譜玻璃。第五章首先制備一系列GeSe_2-Ga_2Se_3-CsBr系統(tǒng)小尺寸(直徑φ9)硫鹵玻璃樣品,使用儀器測試與數(shù)值計算曲線擬合等輔助手段對樣品的物理性能、熱穩(wěn)定性和光學特性進行研究和討論。結(jié)果表明,GeSe_2-Ga_2Se_3-CsBr具有良好的透過性能,滿足其3個窗口的設計需求,同時熱學性能也相對較穩(wěn)定。通過優(yōu)化設計,選取60GeSe_2-25Ga_2Se_3-15CsBr組分作為大尺寸多光譜玻璃制備的主要成份。采用熔融-淬冷制備傳統(tǒng)工藝,研發(fā)提純新工藝,制備了60GeSe_2-25Ga_2Se_3-15CsBr大尺寸(φ30)的高品質(zhì)多光譜硫鹵玻璃。第六章在Ge-Ga-Se系統(tǒng)中引入RbBr,制備了GeSe_2-Ga_2Se_3-RbBr新型三元系統(tǒng)硫鹵玻璃樣品,填補了含Rb硫鹵玻璃的研究空白,確定了其玻璃形成區(qū),同時對新型玻璃樣品的主要物理參數(shù)、熱學性能以及光學特性等進行了系統(tǒng)研究討論,為此類玻璃的進一步應用奠定堅實的基礎。第七章結(jié)論總結(jié)論文中的研究成果,同時指出在未來研究過程需要改進完善之處。
[Abstract]:In recent years, IR technology plays an increasingly important role in national defense, space technology and economic modernization.With the strong growth of infrared market and the continuous development of new applications, the demand for visible to infrared multispectral materials is also increasing.As a multispectral material, thiohalide glass not only has a wide transmission range in the infrared band, but also extends to some visible light bands, and its performance can be adjusted with the component.Wide spectrum transmission and low cost have attracted the attention of researchers and application manufacturers.In this paper, a series of Ge-InGe-Ge-Ce-CsBr-GeGa-In-Se-CsBr-Ge-Ge-Se-RbBr system thiohalide glasses have been prepared. The physical properties, thermal stability and optical properties of the samples have been studied and discussed by means of instrumental test and numerical calculation curve fitting.The 60GeSe_2-25Ga_2Se_3-15CsBr component with good properties was selected as the preparation of large scale glass samples to find the multispectral glass materials with good performance and low cost.The first chapter is the introduction. Firstly, the multispectral glass materials and sulfur glasses are briefly summarized, their development history and research status are introduced, and the content, method, purpose and significance of this work are put forward.In the second chapter, some common properties of se based multispectral sulfur glasses, such as glassy properties and optical properties, are introduced briefly.At the same time, the theoretical basis of performance parameter calculation is briefly reviewed.In chapter 3, the research methods of se based multispectral sulfur (halide) glasses are introduced, including the preparation process of traditional sulfur glasses and the testing of the properties of glass samples, including physical, thermal and optical properties.In chapter 4, the composition and optimization of multispectral sulfur glass are studied. Firstly, the properties of Ge-InSe-CsBr and Ge-Ga-In-Se-CsBr are studied and analyzed respectively.The results show that the Ga-doped glass has advantages not only in cost but also in properties, including physical properties, thermal stability and optical properties.Therefore, Ge-Ga-Se glass system is selected to prepare large size (diameter 蠁 30 and above) multispectral glass.In chapter 5, a series of small size (diameter 蠁 9) thiohalide glass samples of GeSe_2-Ga_2Se_3-CsBr system are prepared. The physical properties, thermal stability and optical properties of the samples are studied and discussed by means of instrumental test and numerical calculation curve fitting.The results show that GeSe2-GaS _ 2Se3-CsBr has good permeability and meets the design requirements of the three windows, and the thermal performance is relatively stable.The 60GeSe_2-25Ga_2Se_3-15CsBr component was selected as the main component in the preparation of large scale multi-spectral glass by optimal design.High quality multi-spectral thiohalide glasses with large size (蠁 30) of 60GeSe_2-25Ga_2Se_3-15CsBr were prepared by using the traditional melt-quenching process and a new process of purification.In the sixth chapter, we introduce RbBrs into Ge-Ga-Se system to prepare the GeSe_2-Ga_2Se_3-RbBr new ternary system thiohalide glass sample, fill the blank of the research of the Rb-containing thiohalide glass, determine the glass forming zone, and at the same time, the main physical parameters of the new glass sample are determined.The thermal properties and optical properties are systematically studied and discussed, which lays a solid foundation for the further application of this kind of glass.Chapter seven summarizes the research results and points out that the future research process needs to be improved.
