Abstract

Zinc oxide (ZnO) is a semiconductor with various physicochemical properties allowing its use in a wide range of technological applications. The aim of this work is to study nanocrystalline ZnO thin-film deposited using zinc salt which is dissolved in pure ionic liquids (ILs). The latter play a dual role: solvent and supporting electrolyte. Most of ILs have a large electrochemical window and sufficient ionic conductivity. In this work, four hydrophobic ILs, based on 1-alkyl-3-methylimidazoliums bis(trifluoromethylsulfonyl)imide were synthetized and characterized to highlight the effect of the length of the cationic alkyl chain on the morphological, structural and optical properties of nanocrystalline ZnO deposits. Grain growth and its arrangement are affected by the length of the cation alkyl chain of ILs, that act as model agents during electroplating. The electrochemical properties of the produced thin layers were also studied.

非质子离子液体中ZnO薄膜的电化学沉积:阳离子烷基链长度的影响

氧化锌(ZnO)是一种具有多种物理化学性质的半导体，具有广泛的技术应用。本工作的目的是研究用溶解在纯离子液体中的锌盐沉积纳米晶ZnO薄膜。后者起着溶剂和支撑电解质的双重作用。大多数离子离子具有较大的电化学窗口和足够的离子电导率。本文合成了4个基于1-烷基-3-甲基咪唑双(三氟甲基磺酰基)亚胺的疏水il，并对其进行了表征，以突出阳离子烷基链长度对纳米晶ZnO镀层形貌、结构和光学性能的影响。在电镀过程中，阳离子烷基链的长度会影响晶粒的生长和排列。并对制备的薄层的电化学性能进行了研究。
