利用长程表面等离子体共振（LRSPR）增强偶氮苯染料芝加哥天蓝6B（CSB）的光异构化。在带有金属膜的光栅衬底上制备了用于LRSPR的CSB薄膜，研究了其在白色光照射前后的光透射特性。p偏振白色光照射后，透射光发生了明显的变化，这种变化归因于强电场作用下LRSPR引起的CSB光致异构化。此外，与标准SPR相比，LRSPR的效果显著。
Enhancement of photoisomerization of Azobenzene dye Chicago Sky Blue 6B (CSB) was attempted using long-range surface plasmon resonance (LRSPR). The CSB film was prepared on a grating substrate with metal film for LRSPR, and its transmission light property was investigated before and after white light irradiation for photoisomerization. The transmission light was markedly changed by irradiation of p-polarized white light, and the change was attributed to photoisomerization of CSB induced by LRSPR which accompanies an intense electric field. Furthermore, the effect of LRSPR was significant compared to standard SPR.
