Emission lights due to surface plasmon (SP) excitations have been investigated in order to develop organic devices such as sensors. SPs are a coupling mode of free electrons and light, and they can be resonantly excited on metal surfaces in the Kretschmann and the Otto configurations by electromagnetic waves due to the total reflection of a p-polarized laser beam. Various nanostructured organic ultrathin films were fabricated, and the SP excitations and emission lights were examined in the Kretschmann configuration of prism/metal thin film/nanostructured ultrathin film structure for the attenuated total reflection (ATR) method.Molecular aligned thin films were prepared using a rubbing method, and it was found that the ATR and SP emission light properties depend on the molecular orientation. It was considered that the SP excitations can be controlled by molecular alignments. Prism/metal thin film/dielectric thin film/metal thin film structure with two metal thin layers for SP excitation … More s in both Kretschmann and Otto configurations was also prepared, and the ATR and SP emission light properties were measured for the structures with and without a luminescent dye molecular layer. The intensity of the emission light from the structure with the luminescent dye molecular layer was much larger than that from the structure without the luminescent dye molecular layer. The emission lights were related to the photoluminescence of the dyes, and the intensity and the spectra strongly depended on the emission angles. Adsorptions of polymer spheres containing luminescent dye molecules were also evaluated using SP emission light measurements and the SP emission lights were expected as new sensing technique. Polymer films with organic microspheres containing luminescent dye molecules were also prepared and the ATR and SP emission light properties were measured. The polymer sample was exposed to dry and wet gas alternately, and the ATR and SP emission light properties after exposure to dry and wet gas alternately were reproducible. It was found that the SP emission lights were useful for the development of humidity sensors.From these results, it is considered that SP excitations and emission lights can be controlled by nanostructured alignments of luminescent dye molecules and are useful for the application to various sensors and new optical devices.

为了开发传感器等有机器件，人们对表面等离子体 (SP) 激发产生的发射光进行了研究。 SPs是自由电子和光的耦合模式，由于p偏振激光束的全反射，它们可以在Kretschmann和Otto构型的金属表面上被电磁波共振激发。制备了各种纳米结构有机超薄膜，并通过衰减全反射（ATR）方法在棱镜/金属薄膜/纳米结构超薄膜结构的Kretschmann配置中检查了SP激发和发射光。采用摩擦法制备了分子取向薄膜，发现ATR和SP发射光性质取决于分子取向。人们认为SP激发可以通过分子排列来控制。还制备了 Kretschmann 和 Otto 配置中具有两个用于 SP 激发的金属薄层的棱镜/金属薄膜/电介质薄膜/金属薄膜结构，并测量了具有和不具有发光染料分子层的结构的 ATR 和 SP 发射光性能。具有发光染料分子层的结构的发射光强度远大于不具有发光染料分子层的结构的发射光强度。发射光与染料的光致发光有关，强度和光谱很大程度上取决于发射角。还使用 SP 发射光测量来评估含有发光染料分子的聚合物球的吸附，并且 SP 发射光有望成为新的传感技术。还制备了含有发光染料分子的有机微球的聚合物薄膜，并测量了 ATR 和 SP 发射光性能。将聚合物样品交替暴露于干湿气体中，交替暴露于干湿气体后的ATR和SP发射光性能是可再现的。研究发现，SP发射光对于湿度传感器的开发很有用。从这些结果来看，人们认为SP激发和发射光可以通过发光染料分子的纳米结构排列来控制，并且可用于各种传感器和新型光学器件的应用。较少的
