研究了光学透明金刚石电极（OTE）对二茂铁的光谱电化学响应性。独立式机械抛光掺硼金刚石圆盘（厚 0.38 毫米，直径 8 毫米）用作紫外-可见光透射光谱电化学测量的 OTE。构建了一种专门设计的薄层光谱电化学电池用于测量，其中二茂铁通过单电子氧化还原反应电氧化为铁离子。在电磁波谱的紫外（λ=252、285nm）区域对氧化反应产物进行光谱监测。对于这种类型的金刚石 OTE，观察到了明确且高度稳定的光谱电化学响应。结果表明，金刚石是一种用于光谱电化学研究非水氧化还原反应的有用 OTE 材料。
The spectroelectrochemical responsiveness of an optically transparent diamond electrode (OTE) toward ferrocene was investigated. A freestanding, mechanically polished, boron-doped diamond disk (0.38mm thick and 8mm in diameter) served as the OTE for UV-Vis transmission spectroelectrochemical measurements. A specially designed, thin-layer spectroelectrochemical cell was constructed for the measurements in which ferrocene was electrooxidized to ferricinium ion via a one-electron redox reaction. The oxidation reaction product was spectroscopically monitored in the ultraviolet (λ=252, 285nm) region of the electromagnetic spectrum. Well-defined and highly stable spectroelectrochemical responses were observed for this type of diamond OTE. The results indicate that diamond is a useful OTE material for spectroelectrochemically studying nonaqueous redox reactions.
