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.

我们研究了具有光电和电存储效应的器件的结构。为了我们的目的，应该实现光致变色和电致变色效应之间的有效耦合。我们报道过，光致变色增强是通过添加一些高分子材料实现的。这种额外的聚合物也可用于制造薄膜器件。因此，我们认为溶胶-凝胶法和脱水玻璃化法可能是制作这种器件的合适方法，因此，我们用时间分辨表面波测量方法研究了钨酸与明胶和硅胶凝胶化过程中表面波的性质。对于结果，我们使用了倒谱分析，并得到了有用的信息，两个波模式的共存。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，凝胶中溶剂与聚合物网络的相互作用对脱水过程的特性有很大的影响，但我们无法达到实用的高灵敏度。薄膜的改进和结构的优化是必要的。
