Abstract

一般光學顯微鏡受限於光學繞射性質,對於奈米尺寸下的解析度力有未逮。近場光學顯微鏡能夠突破光學繞射極限,將解析力提升至奈米尺度,對於奈米尺度下的光學性質能夠有更進一步的研究。而共焦拉曼光譜相較於傳統拉曼光譜能夠有效的提高其解析能力,並具有對材料定域化量測的能力,提供了研究材料微觀的光學性質與化學組成的分布。本文中將分別介紹利用近場光學顯微鏡研究高分子-奈米粒子混成太陽能電池薄膜材料在奈米尺度下的光吸收性質,以及利用共聚焦拉曼光譜分析太陽能電池元件的薄膜形態變化與成分分布。
The optical diffraction limits the spatial resolution of conventional optical microscope at nanoscale. The development of scanning near-field optical microscope (SNOM) has resolved this limitation and exhibited the ability of imaging with nano-scale resolution. The SNOM has become a popular technique to observe the optical properties of nano-scaled materials. Comparing with traditional Raman spectrum, the confocal Raman spectrum provides optical and chemical mapping capability with high resolution. In this article, we discuss the studies of polymer nanoparticle hybrid materials for photovoltaic devices using these two techniques. The SNOM was used to investigate the nanoscale optical properties of the hybrid material. The confocal Raman spectrum was used to evaluate the morphology change and component distribution.
