Titanium dioxide nanocomposites were synthesized in hierarchical architectures through the use of a 1,4-dihydroxyanthraquinone photosensitizer. In the first step, the dye was either incorporated into the TiO core or adsorbed on its surface. In the subsequent phase, both structures were covered with an outer layer of titanium dioxide. The structure, morphology, aggregation, spectroscopic, and electrochemical properties of the synthesized TiO -based materials are presented with emphasis on the photosensitization and the photocurrent switching phenomena, which are also discussed within the context of the optical logic gates implementation and fuzzy logic systems operation. We present three different interpretations of the photocurrent action spectra yielding binary, ternary, or fuzzy logic circuits.
通过使用1,4 - 二羟基蒽醌光敏剂，在分级结构中合成了二氧化钛纳米复合材料。第一步，将染料掺入TiO核中或吸附在其表面。在随后的阶段，两种结构都被二氧化钛外层覆盖。介绍了合成的TiO基材料的结构、形态、聚集、光谱和电化学性质，重点是光敏化和光电流开关现象，这些现象也在光学逻辑门实现和模糊逻辑系统操作的背景下进行了讨论。我们给出了光电流作用光谱的三种不同解释，产生二元、三元或模糊逻辑电路。
