Abstract

We investigated enhancing the electro-optical properties of thin films by doping them with graphene oxide (GO) following the fabrication of a zirconium strontium tin oxide solution via the sol–gel method. GO was doped into inorganic materials at 0, 5, and 15 wt%, respectively. The characteristics of the resulting thin films were analyzed based on doping ratio. Our study confirmed significant improvements in electrical properties through accelerated reaction speeds via response time vs. transmission measurements and notably enhanced T₉₀ transmittance values in voltage–transmission measurements. X-ray photoelectron spectroscopy was employed to analyze the chemical composition of the thin film surfaces, revealing the impact of graphene’s carbon isomer nature and the oxygen environment. Furthermore, changes in surface roughness were assessed using atomic force microscopy, validating the alterations in properties. Finally, the thin film’s suitability for display devices was confirmed through transmittance measurements.

含有氧化石墨烯的溶胶-凝胶法氧化锆锶锡薄膜的改进电光特性

我们研究了在通过溶胶-凝胶法制备锆锶锡氧化物溶液后，通过在薄膜中掺杂氧化石墨烯（GO）来增强薄膜的电光特性。无机材料中的 GO 掺杂量分别为 0、5 和 15 wt%。根据掺杂比例分析了所得薄膜的特性。我们的研究证实，通过响应时间与透射率测量，反应速度加快，电学特性明显改善；通过电压-透射测量，T90 透射率值显著提高。我们采用 X 射线光电子能谱分析了薄膜表面的化学成分，揭示了石墨烯碳异构体性质和氧环境的影响。此外，还利用原子力显微镜评估了表面粗糙度的变化，验证了性质的改变。最后，通过透射率测量确认了薄膜是否适合用于显示设备。

期刊介绍： The objective of the Journal of Nanoparticle Research is to disseminate knowledge of the physical, chemical and biological phenomena and processes in structures that have at least one lengthscale ranging from molecular to approximately 100 nm (or submicron in some situations), and exhibit improved and novel properties that are a direct result of their small size. Nanoparticle research is a key component of nanoscience, nanoengineering and nanotechnology. The focus of the Journal is on the specific concepts, properties, phenomena, and processes related to particles, tubes, layers, macromolecules, clusters and other finite structures of the nanoscale size range. Synthesis, assembly, transport, reactivity, and stability of such structures are considered. Development of in-situ and ex-situ instrumentation for characterization of nanoparticles and their interfaces should be based on new principles for probing properties and phenomena not well understood at the nanometer scale. Modeling and simulation may include atom-based quantum mechanics; molecular dynamics; single-particle, multi-body and continuum based models; fractals; other methods suitable for modeling particle synthesis, assembling and interaction processes. Realization and application of systems, structures and devices with novel functions obtained via precursor nanoparticles is emphasized. Approaches may include gas-, liquid-, solid-, and vacuum-based processes, size reduction, chemical- and bio-self assembly. Contributions include utilization of nanoparticle systems for enhancing a phenomenon or process and particle assembling into hierarchical structures, as well as formulation and the administration of drugs. Synergistic approaches originating from different disciplines and technologies, and interaction between the research providers and users in this field, are encouraged.
