We investigated photo-induced electrochemical reactions in a liquid crystal cell with thin silver-sulfide layer. As a result, two kinds of needle-like crystal formation were observed. One was formed by a carbon compound only. Another was formed by the carbon compound with a silver core. It is expected that the silver core was formed by reduced silver ions generated by photo irradiation, and then the core was surrounded by the carbon compounds, subsequently. We also investigated metal-coated films with fine structure, which is formed by small particles, to observe the electrochemical reaction on the metal surface. It is expected that the metal surface or interface modulation based on the electrochemical reaction is observed in the spectral changes and these will be applied for sensing devices in the future.

我们研究了具有薄硫化银层的液晶盒中的光诱导电化学反应。结果，观察到两种针状晶体形成。一个是由碳化合物形成的。另一种是由碳化合物与银核心形成的。预期银核是通过光照射产生的还原银离子形成的，然后该核随后被碳化合物包围。我们还研究了由小颗粒形成的具有精细结构的金属涂层膜，以观察金属表面的电化学反应。可以预见，基于电化学反应的金属表面或界面调制将在光谱变化中被观察到，这些将在未来的传感器件中得到应用。
