| Research Abstract |
The research on organic semiconductor devices, such as organic light-emitting diodes and organic thin-film photovoltaics, have been significantly developed recently. However, the light control by organic semiconductor thin-films themselves has never been explored. In this study, we fabricated and analyzed the organic semiconductor films in view of the molecular orientation and polarizability, and achieved a refractive index difference of 0.58, which is a very large value for organic materials. Using the films with the large refractive index difference, we also realized organic mirrors having a reflectivity of 98% and a reflection bandwidth of >100 nm, and demonstrated the lightpropagation control and the photoconductivity. We believe that our results of the light control by organic semiconductors offer new degrees of freedom in optical design of organicsemiconductor devices.
