中文摘要
由于表面等离子体激元(SP)激发的发射光已被研究,以开发有机器件,如传感器。SPs是自由电子和光的耦合模式,并且由于p偏振激光束的全反射,它们可以在Kretschmann和Otto配置中被电磁波共振激发在金属表面上。制备了各种纳米结构的有机薄膜,采用衰减全反射(ATR)方法研究了棱镜/金属薄膜/纳米结构有机薄膜的Kretschmann结构中的SP激发光和发射光,采用摩擦法制备了分子取向薄膜,发现ATR和SP发射光的性质依赖于分子取向。有人认为,SP激发可以控制的分子排列。用于SP激励的具有两个金属薄层的棱镜/金属薄膜/电介质薄膜/金属薄膜结构 ...更多信息 还制备了Kretschmann和Otto构型的结构,并测量了具有和不具有发光染料分子层的结构的ATR和SP发射光特性。来自具有发光染料分子层的结构的发射光的强度比来自没有发光染料分子层的结构的发射光的强度大得多。染料的发射光与染料的光致发光有关,其强度和光谱与发射角密切相关。利用SP发光法研究了含荧光染料分子的聚合物微球对染料的吸附性能,并展望了SP发光法作为一种新的传感技术的前景。制备了含荧光染料分子的有机微球聚合物薄膜,并测量了ATR和SP发光性能。将聚合物样品交替暴露于干气体和湿气,并且交替暴露于干气体和湿气之后的ATR和SP发射光性质是可再现的。研究结果表明,SP激发光和发射光可以通过发光染料分子的纳米结构排列来控制,并可用于各种传感器和新型光学器件。少
英文摘要
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.
