TL;DR: In this paper, a new approach for the fabrication of reduced graphene oxide (rGO) multilayers which can be used for transparent and conducting thin films was developed by using layer-by-layer assembly of positively and negatively charged rGO sheets, which could provide highly controllable thin films in terms of thickness, transmittance, and sheet resistance.

TL;DR: The surface plasmon effect on polymer solar cells and polymer light-emitting diodes is demonstrated by using metal nanoparticles prepared from block copolymer templates, resulting in a significant surface plAsmon effect in the optoelectronic devices.

TL;DR: The assembly of reduced graphene oxide and fullerene into hybrid wires was successfully performed by employing the liquid-liquid interfacial precipitation method, and the I(ds)-V(g) curves of the hybrid wires exhibited p-type semiconducting behavior both in vacuum and in air.

TL;DR: By obtaining the phase separated domains in thin film of the resulting block copolymer, it is possible to suppress energy transfer from PVK as wide bandgap units to P3HT as low bandgap blocks, yielding dual emissions for white electroluminescence with CIE coordination.

TL;DR: In this paper, the synthesis and characterization of new series of fluorene based polymers with carbazole and oxadiazole pendants for the generation of the white emission out of the EL device were reported.
