The optical properties of electrochemically deposited Prussian blue (PB) on an indium tin oxide (ITO)-coated glass electrode (glass/ITO) were investigated at different ammonium ion concentrations (0.01 M to 0.1 M) in order to use this electrode to design an electrochromic sensor sensitive to ammonium ions. The glass/ITO/PB-based structure exhibited a fast optical-absorbance-based response towards ammonium ions. A protocol for simple regeneration of the glass/ITO/PB structure after the determination of ammonium ion concentration has been developed.

走向电致变色铵离子传感器

为了在不同的铵离子浓度（0.01 M至0.1 M）下使用电化学电极沉积的普鲁士蓝（PB）在不同的铵离子浓度（0.01 M至0.1 M）上的光学特性进行了研究。对铵离子敏感的电致变色传感器。基于玻璃/ ITO / PB的结构对铵离子表现出快速的基于光吸收的响应。已经开发出一种在确定铵离子浓度后简单再生玻璃/ ITO / PB结构的方案。
