In this data in brief article dataset of plasma-assisted nitrogen doping of a binderless, spin-coated CuO-NiO mixed oxide thin film was presented (Palmer et al., 2020). A comparison of the CuO, N-CuO/CuO, CuO:NiO and N-CuO/CuO:NiO are presented. The as prepared films were used for the application of a glucose sensor. The nitrogen doped species, generated during plasma ignition, resulted in a beneficial phase transformation of CuO to CuO. Characterisation techniques such as XPS, particle size distribution and EIS techniques were utilized to study the morphology, structural features, doping profile and electrical properties of the various developed electrodes. The electrochemical performance of the thin film sensors was tested using cyclic voltammetry and chronoamperometry. The CuO exhibited a sensitivity of 830 µA/mM cm up to 1.65 mM of glucose, N-CuO/CuO had a linear range up to 1.91 mM with a sensitivity of 873 µA/mM cm and the CuO:NiO electrode had a linear range up to 1.65 mM with a sensitivity of 1103 µA/mM.cm respectively. A detailed description of the methodology used is provided below.
在这篇数据简报文章中，展示了等离子体辅助对无粘合剂、旋涂的CuO-NiO混合氧化物薄膜进行氮掺杂的数据集（帕尔默等人，2020年）。文中对CuO、N-CuO/CuO、CuO:NiO和N-CuO/CuO:NiO进行了比较。所制备的薄膜用于葡萄糖传感器的应用。等离子体点火过程中产生的氮掺杂物种导致了CuO向CuO的有益相变。利用XPS、粒度分布和EIS等表征技术研究了各种制备电极的形貌、结构特征、掺杂分布和电学性能。使用循环伏安法和计时电流法测试了薄膜传感器的电化学性能。CuO在葡萄糖浓度高达1.65 mM时表现出830 µA/mM·cm的灵敏度，N-CuO/CuO的线性范围高达1.91 mM，灵敏度为873 µA/mM·cm，而CuO:NiO电极的线性范围高达1.65 mM，灵敏度分别为1103 µA/mM·cm。下面提供了所用方法的详细描述。
