Nanofibers, which are fibers with diameters less than 1 μm, are attracting attention as base materials for gas or liquid filters, light-weight and transparent electrodes, biological scaffolds, etc. We are focusing on developing a novel optoelectronic device composed of nanofibers with doping organic semiconductor materials* to the fibers.
*Organic semiconductor materials: Organic materials which show semiconducting properties. They are used for Organic Light Emitting Diodes (OLED), Organic Photovoltaics (OPV), Organic Field-Effect Transistor (OFET), etc.
Theme1：Development of optoelectronic devices using polymer nanofibers
Plastic nanofibers are very small and light-weight. Besides, they have potential for developing unique optoelectronic properties because the fibers have diameters equivalent to wavelength of visible light or less. We are focusing on investigating light-emitting properties inside the fibers doping organic semiconductor materials. Moreover, we are developing a novel optoelectronic device composed of nanofibers.
