The titanium dioxide (TiO(2)) nanorod-decorated graphene sheets photocatalysts with different TiO(2) nanorods population have been synthesized by a simple non-hydrolytic sol-gel approach. Electron microscopy and X-ray diffraction analysis indicated that the TiO(2) nanorods are well-dispersed and successfully anchored on the graphene sheet surface through(More)
UNLABELLED We report the self-assembly of poly(3,4-ethylene dioxythiophene):poly(styrenesulfonate) ( PEDOT PSS) organogel films incorporating graphene quantum dots (GQDs). Because of the electrostatic interaction between the GQDs and the PEDOT chains, GQD@PEDOT core-shell nanostructures are readily formed. We demonstrate that the GQDs affect the(More)
High-performance Förster resonance energy transfer (FRET)-based dye-sensitized solar cells (DSSCs) have been successfully fabricated through the optimized design of a CdSe/CdS quantum-dot (QD) donor and a dye acceptor. This simple approach enables quantum dots and dyes to simultaneously utilize the wide solar spectrum, thereby resulting in high conversion(More)
