摘要

背景。氧化锌(ZnO)是设计半导体辐射源和探测器的一种很有前途的材料。基于ZnO的薄膜被认为是光电器件的可能元素,可以用来影响其光学特性。目前,制备ZnO薄膜的方法多种多样,但如何获得高质量、低成本的ZnO薄膜仍是一个实际需要解决的科学和工程问题。因此,该方向的研究和对ZnO薄膜的合成提出建议是迫切需要的。工作目的:本工作的目的是通过溶胶-凝胶技术制备ZnO薄膜,评价其结构和光学性能,并估计紫外线辐射对所得薄膜结构和光学特性的影响。技术和方法论。研究了制备ZnO薄膜的工艺。介绍了溶胶-凝胶法制备这种薄膜的过程。对实验所得的薄膜进行了视觉分析。实验研究了ZnO薄膜的光学性能。特别分析了薄膜制备阶段使用的紫外辐射对薄膜吸收光学范围内辐射特性的影响。采用溶胶-凝胶法制备ZnO薄膜。在石英衬底上形成ZnO薄膜。在不受辐射影响的情况下,在薄膜中观察到ZnO纳米颗粒的形成。在480℃的最后热处理阶段使用紫外辐射,形成了质量更高的ZnO薄膜,颗粒尺寸减小。使用x射线荧光分析对薄膜的化学成分进行分析,发现在形成的薄膜中存在锌和氧,以及微不足道的碳含量,这与使用石英作为衬底有关。得到了入射到ZnO薄膜上的辐射波长在200 ~ 450 nm范围内与ZnO薄膜透射能力的关系。结果表明,在热处理阶段,经紫外线照射的薄膜中,吸收边对应的截止波长值发生了位移,由此计算出的带隙减小。结论:总结本研究的结果,我们可以强调,在最后热处理阶段紫外线辐射对溶胶-凝胶法制备ZnO薄膜的影响,导致薄膜质量的提高和光学性质的改变,特别是吸收阈值对应的能量降低。

Optic properties of ZnO films grown by sol-gel technique
Background. Zinc oxide (ZnO) is a promising material for designing the semiconductor radiation sources and detectors in the region of short wavelengths of the optical range. Films based on ZnO are considered as possible elements of optoelectronic devices that can be used to influence their optical properties. Nowadays, the methods of making such films are quite diverse, however, obtaining high-quality and inexpensive ZnO films remains an actual scientific and engineering task that needs to be solved. Thus, the research in this direction and the development of recommendations on the synthesis of ZnO films is urgent. Purpose of Work. The aim of the work is to obtain ZnO films by the sol-gel technique, to evaluate their structure and optical properties and to estimate the affect of ultraviolet radiation on the structure and optical characteristics of the obtained films. Techniques and Methodology. The process of obtaining ZnO films is considered. The process of obtaining such films by sol-gel technique is described. A visual analysis of the experimentally obtained films has been carried out. The optical properties of ZnO films were experimentally examined. In particular, the influence of ultraviolet radiation used at the stage of obtaining films on the features of their ability to absorb radiation in the optical range is analyzed. Results. ZnO films were grown experimentally by sol-gel technique. ZnO films were formed on quartz substrates. The formation of ZnO nanoparticles is observed in the films obtained without the influence of radiation. The usage of ultraviolet radiation at the stage of the final heat treatment at a temperature of 480 °C leads to the formation of a higher quality ZnO film and a decrease in the size of the granules. Analysis of the chemical composition of the films using X-ray fluorescence analysis shows the presence of zinc and oxygen in the formed films, as well as insignificant carbon content, which is associated with the use of quartz as substrates. The dependencies of the transmission capacity of ZnO films on the wavelength of radiation incident on the film in the range of 200-450 nm are obtained. It is shown that in films exposed to ultraviolet radiation at the stage of heat treatment, there is a shift in the value of the cut-off wavelength corresponding to the absorption edge and, accordingly, a decrease in the band gap calculated from the results of the experiment. Conclusions: To summarize the results of the research we can highlight that the influence of ultraviolet radiation at the stage of the final heat treatment on ZnO films formed by sol-gel method leads to an improvement in the quality of the films and to a change in their optical properties, in particular, a decrease in the energy corresponding to the absorption threshold.
