【摘要】：低輻射鍍膜玻璃(Low emissivity coated glass)又稱之為Low-E玻璃,它對(duì)波長為2.5μm-25μm的紅外線具有較高的反射率,而對(duì)可見光具有很高的透過率。它是一種優(yōu)良的環(huán)保節(jié)能玻璃。隨著對(duì)Low-E玻璃的深入研究,人們對(duì)其材料結(jié)構(gòu)、光學(xué)特性等認(rèn)識(shí)越來越深,其潛在的應(yīng)用價(jià)值也被慢慢發(fā)掘。本論文以發(fā)展Low-E玻璃的生產(chǎn)技術(shù),產(chǎn)品性能及應(yīng)用為目標(biāo),從其光學(xué)特性出發(fā),對(duì)其光學(xué)常數(shù)、光學(xué)機(jī)理進(jìn)行了研究;并對(duì)Low-E玻璃的表面等離子體共振特性和具有自潔凈性能的低輻射玻璃進(jìn)行了研究。本文主要分為五個(gè)部分:第一部分,主要描述了Low-E玻璃的概念、低輻射原理、Low-E玻璃種類、生產(chǎn)工藝等。重點(diǎn)介紹了國內(nèi)外的研究現(xiàn)狀,并且給出了本論文的選題依據(jù)。第二部分,從Lorentz雙振子模型和Cauchy模型出發(fā),對(duì)Low-E玻璃各層光學(xué)色散特性進(jìn)行描述。建立橢圓偏振法測量在線Low-E玻璃光學(xué)常數(shù)的理論模型,研究了在線Low-E玻璃功能層和過渡層在可見-近紅外波段的光學(xué)常數(shù)。擬合橢偏參數(shù)得到在線Low-E玻璃各層厚度和光學(xué)常數(shù),并對(duì)擬合的結(jié)果進(jìn)行實(shí)驗(yàn)驗(yàn)證。第三部分,通過第二部分的研究發(fā)現(xiàn),在線Low-E玻璃功能層的光學(xué)常數(shù)與金屬相似,從理論上推導(dǎo)出其可以作為激發(fā)表面等離子體共振的材料。我們?cè)O(shè)計(jì)了仿真模型,用傳輸矩陣的方法對(duì)其進(jìn)行了理論仿真。研究發(fā)現(xiàn)其能夠激發(fā)表面等離子體共振,相比金屬,它能夠激發(fā)的波長有很大不同。第四部分,我們采用磁控濺射的方法在低輻射玻璃表面鍍上TiO2薄膜,設(shè)計(jì)了一種具有自潔凈性能的低輻射玻璃,優(yōu)化工藝條件,并對(duì)其低輻射性能和自潔凈性能進(jìn)行了表征。第五部分,是對(duì)本論文工作的總結(jié)以及未來的展望�？偠灾�,本論文對(duì)Low-E玻璃光學(xué)機(jī)理和應(yīng)用前景進(jìn)行了深入研究,對(duì)其發(fā)展和應(yīng)用有一定的借鑒意義。
[Abstract]:Low emissivity coated glassglass, also known as Low-E glass, has high reflectivity to infrared light with wavelength of 2.5 渭 m to 25 渭 m. But it has a high transmittance to visible light. It is a kind of excellent environmental protection and energy saving glass. With the in-depth study of Low-E glass, people have a deeper and deeper understanding of its material structure, optical properties and so on. The potential application value of Low-E glass has been gradually explored. In order to develop the production technology, product performance and application of Low-E glass, the optical constant and optical mechanism of Low-E glass have been studied from its optical properties. The surface plasmon resonance (SPR) characteristics of Low-E glass and low radiation glass with self-cleanness are studied. This paper is divided into five parts: the first part mainly describes the concept of Low-E glass and the low radiation principle of Low-E glass. This paper introduces the current research situation at home and abroad, and gives the basis of this thesis. The second part is based on the Lorentz dual oscillator model and Cauchy model. The optical dispersion characteristics of each layer of Low-E glass are described. A theoretical model for measuring the optical constants of Low-E glass by elliptical polarization method is established. The optical constants of the functional layer and transition layer of on-line Low-E glass in visible and near infrared band are studied. The thickness and optical constants of each layer of on-line Low-E glass are obtained by fitting ellipsometry parameters, and the experimental results are verified. In the second part, it is found that the optical constants of the functional layer of on-line Low-E glass are similar to those of metals, which can be used to excite surface plasmon resonance theoretically. The theoretical simulation is carried out with the method of transfer matrix. It is found that it can excite surface plasmon resonance (SPR), and the wavelength it can excite is quite different from that of metal. TiO2 thin films were deposited on the surface of low radiation glass by magnetron sputtering. A kind of low radiation glass with self-cleaning property was designed. The process conditions were optimized and its low radiation and self-cleaning properties were characterized. All in all, the optical mechanism and application prospect of Low-E glass have been deeply studied in this paper, which has some reference significance for its development and application.
