Abstract
We performed an electrochromic investigation to optimize the composition of reactive magnetron-sputtered mixed layers of zinc oxide and tin oxide (ZnO-SnO2). Deposition experiments were conducted as a combinatorial material synthesis approach. The binary system for the samples of SnO2-ZnO represented the full composition range. The coloration efficiency (CE) was determined for the mixed oxide films with the simultaneous measurement of layer transmittance, in a conventional three-electrode configuration, and an electric current was applied by using organic propylene carbonate electrolyte cells. The optical parameters and composition were measured and mapped by using spectroscopic ellipsometry (SE). Scanning Electron Microscopy (SEM) and Energy-Dispersive X-ray Spectroscopy (EDS) measurements were carried out to check the SE results, for (TiO2-SnO2). Pure metal targets were placed separately from each other, and the indium-tin-oxide (ITO)-covered glass samples and Si-probes on a glass holder were moved under the two separated targets (Zn and Sn) in a reactive argon-oxygen (Ar-O2) gas mixture. This combinatorial process ensured that all the compositions (from 0 to 100%) were achieved in the same sputtering chamber after one sputtering preparation cycle. The CE data evaluated from the electro-optical measurements plotted against the composition displayed a characteristic maximum at around 29% ZnO. The accuracy of our combinatorial approach was 5%.
我们进行了一项电致变色研究，以优化氧化锌和氧化锡（ZnO-SnO2）反应磁控溅射混合层的组成。沉积实验采用组合材料合成法进行。SnO2-ZnO 样品的二元体系代表了整个成分范围。混合氧化物薄膜的着色效率（CE）是通过在传统的三电极配置中同时测量层透射率和使用有机碳酸丙烯酯电解质电池施加电流来确定的。使用光谱椭偏仪（SE）测量并绘制了光学参数和成分图。扫描电子显微镜（SEM）和能量色散 X 射线光谱（EDS）测量用于检查（TiO2-SnO2）的 SE 结果。纯金属靶彼此分开放置，在反应性氩-氧（Ar-O2）混合气体中，玻璃支架上的铟锡氧化物（ITO）覆盖玻璃样品和硅探针在两个分开的靶（锌和锡）下移动。这种组合过程确保了在一个溅射制备周期后，所有成分（从 0 到 100%）都能在同一溅射室中实现。通过电光测量评估出的 CE 数据与成分的关系图显示，在氧化锌含量为 29% 左右时，CE 值达到了一个特征性的最大值。我们的组合方法的精确度为 5%。
期刊介绍：
The International Journal of Molecular Sciences (ISSN 1422-0067) provides an advanced forum for chemistry, molecular physics (chemical physics and physical chemistry) and molecular biology. It publishes research articles, reviews, communications and short notes. Our aim is to encourage scientists to publish their theoretical and experimental results in as much detail as possible. Therefore, there is no restriction on the length of the papers or the number of electronics supplementary files. For articles with computational results, the full experimental details must be provided so that the results can be reproduced. Electronic files regarding the full details of the calculation and experimental procedure, if unable to be published in a normal way, can be deposited as supplementary material (including animated pictures, videos, interactive Excel sheets, software executables and others).
