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.

已经研究了由于表面等离子体（SP）兴奋而引起的发射灯，以开发有机设备，例如传感器。 SP是游离电子和光的一种耦合模式，由于P极极化激光束的总反射，它们可以在Kretschmann的金属表面和通过电磁波的OTTO构型上共鸣。 Various nanostructured organic ultrathin films were fabricated, and the SP excitements and emission lights were examined in the Kretschmann configuration of prism/metal thin film/nanostructed ultrathin film structure for the attenuated total reflection (ATR) method.Molecular aligned thin film were prepared using a rubbering method, and it was found that the ATR and SP emission light properties depend on the molecular orientation.据认为，SP兴奋可以通过分子比对来控制。还准备了棱镜/金属薄膜/介电薄膜/金属薄膜结构，具有两个金属薄层，可用于兴奋……在Kretschmann和Otto构型中都有更多的S，并且在没有发光的染料分子层的情况下测量了ATR和ATR和SP发射光特性。发光染料分子层发出的发射光强度远大于没有发光染料分子层的结构的强度。发射灯与染料的光亮效有关，强度和光谱强烈取决于发射角。还使用SP发射光测量值评估了含有发光染料分子的聚合物球的吸附，并预计将SP发射灯视为新的灵敏度技术。还制备了具有有机微球的聚合物膜，还制备了ATR和SP发射光的性能。聚合物样品可暴露于干燥和湿气体中，并且可重现暴露于干燥和湿气后的ATR和SP发射光特性。发现SP发射灯对湿度传感器的开发很有用。从这些结果中，可以认为SP兴奋和发射灯可以通过发光染料分子的纳米结构对齐来控制，并且可用于在各种传感器和新的光学设备中应用。较少的
