CuS纳米粒子的电化学发光行为研究

摘要

An ECL emission of CuS NPs in peroxydisulfate was observed during cyclic potential scan from 0 V to - 2.0 V, and its ECL intensity has good linear relationship with the concentration of CuS in the range from 1.5 × 10-5g/mL to 7.7 × 10 -5 g/mL. Moreover, the ECL behaviour of CuS NPs modified Pt disk electrode was also investigated. It was found that the ECL intensity of peroxydisulfate can be enhanced by the CuS NPs.%CuS纳米粒子在过硫酸钾溶液中从0～-2.0 V的循环扫描过程中有较强的电化学发光现象,且发光强度与CuS纳米粒子的浓度在1.5×10-5～7.7×10-5 g/mL范围内呈线性关系.研究了CuS纳米粒子修饰铂电极在过硫酸钾溶液的电化学发光行为,发现CuS纳米粒子修饰铂电极能够增强过硫酸钾溶液的电化学发光强度.该发现为CuS纳米粒子在发光标记及其光电转换器件方面的应用提供理论参考.
