Study of Chargeable Photoelectric Conversion Effect in Tungstic Acid Gel Membrane.

我们研究了具有光电和电存储效应的器件的结构。为了达到我们的目的，必须实现光致变色和电致变色效应之间的有效耦合。正如我们所报道的那样，光致变色增强是通过添加一些聚合物材料来实现的。这些额外的聚合物对于制作薄膜装置也很有用。因此，我们认为溶胶-get法和脱水玻璃法可能是制作该装置的合适方法。因此，我们通过时间分辨表面波测量研究了钨酸、明胶和硅胶凝胶化过程中表面波的性质。对于结果，我们使用倒谱分析，得到了关于两种波模式共存的有用信息。此外，我们还研究了凝胶的脱水过程，这对溶胶-凝胶法的应用具有重要意义。我们发现凝胶中溶剂和聚合物网络的相互作用对脱水过程的特性有很大的影响。然而，我们无法达到对实际应用有用的更高灵敏度。需要对薄膜进行改进，对结构进行优化。

We examined the structure of the device that has photoelectric and electric storage effects. For our purpose, the efficient coupling between photochromic and electrochromic effects should be achieved. As we reported, the photochromic enhancement was achieved by the additives of some polymeric materials. This additional polymers were useful for making the devices of film, too. Because, we thought the sol-get method and the dehydrated glassification might be the suitable methods to make the devices.Thus, we studied the properties of surface waves during the gelation process of tungstic acid and gelatin and silica gel by the time resolved surface wave measurements. For the results, we used cepstrum analyses and got useful information regarding the coexistence of two wave modes. Moreover, we have studied dehydration process of gels, which are important to use the sol-gel method. We found that the feature of the dehydration process has been much affected by the interaction between solvent and polymer networks in the gels.However, we couldn't achieve the higher sensitivity that was useful for the practical application. The improvement of the film and the optimization of the structure is needed.
