A microcomputer program for optical multilayer thin filmsBetts, Kevin Howard January 1985 (has links)
A microcomputer software package was written to calculate the tranmission and reflection characteristics of multilayer thin films on a substrate. The program was written to be as "user-friendly", versatile and modular as possible. To test the program, a transparent oxide-type heat-mirror film capped with an antireflection coating was studied for greenhouse applications. Si0₂ and ZnO were considered as representative antireflection and heat-mirror materials respectively. The results of calculations of heat transfer coefficient and transmittance of the glazing construction
polyethylene/air gap/Si0₂/ZnO/polyethylene are presented. The resulting structure is shown to give a visible light transmission spectrum which closely matches the plant sensitivity curve for plant growth and has higher thermal insulation compared to uncoated polyethylene. / Science, Faculty of / Physics and Astronomy, Department of / Graduate

CHARACTERIZATION OF THE OPTICAL PROPERTIES OF SOME TRANSITION METAL CARBIDES AND NITRIDESShimshock, Richard Paul, 1954- January 1987 (has links)
We established measurement and analysis techniques necessary to investigate the optical properties of some transition metal compounds: specifically the carbides and nitrides of Ti, Zr, and Hf. Two distinct techniques determined the optical constants of these films: a Nestell-Christy method to invert measurements of thickness, reflection, and transmission and a Kramers-Kronig analysis of reflection. The compositions of the samples were evaluated by X-ray diffraction, Auger spectroscopy, scanning electron microprobe analysis, and nuclear analysis. We found it possible to correlate these materials' optical and electronic properties and relate these to compositional changes. The ability to engineer a specific optical response of materials is discussed. Additions of carbon and nitrogen change the optical properties in a specific manner; the roles of these elements as electron donors and their effect on the location and population of the d electron bands with respect to the Fermi level are postulated.

The preparation and characterisation of novel organo-ruthenium Langmuir-Blodgett filmsRichardson, Tim January 1989 (has links)
In recent years, there has been considerable interest in media which exhibit significant non-linear physical properties. The non-linear optical response of many materials has attracted a great deal of attention from the telecommunications industry owing to their possible use for signal processing applications. Also, applications such as thermal imaging depend ultimately upon the proficient operation of the active material within the device structure. Traditionally, inorganic materials such as lithium niobate and strontium barium niobate have been used for non-linear optics and infra-red detection. However, the last decade or so has exposed the potentially high efficiency offered by organic materials which, coupled to the ability to engineer their physical properties by subtle modifications at the molecular level, suggests an exciting and productive future. In order to maintain compatibility with existing integrated optics and display technologies, it is often useful to process the active compound in thin film form. The stringent symmetry requirements imposed upon the molecules and their organisation in the macroscopic structure necessitates the existence of non-centrosymmetric molecular structures for second-order non-linear applications such as those mentioned above. The Langmuir-Blodgett deposition technique enables such assemblies to be constructed by the sequential transfer of organic monomolecular layers from a liquid-air interface onto a solid substrate. The precise control of film thickness and molecular architecture afforded by the technique allow polar multilayer structures to be produced which possess the properties required for highly efficient second-order non-linear physical operation. This thesis describes the development of a series of novel organo-metallic complexes which possess the necessary molecular properties for LB deposition in addition to those required for the observation of a large non-linear response. The complexes offer substantially improved thermal stability over other LB materials, and are thus appealing to the industrial device engineer. Their physical properties have been systematically studied and related to their detailed molecular structure. In particular, optical second-harmonic generation studies have shown that they possess high molecular coefficients and have provided a launching stage for further development. Their high pyroelectric response has attracted much enthusiasm from both industry and academia because of their potential commercial exploitation in thermal imaging devices.
