Hybrid nanostructures that combine inorganic materials and graphene are being developed for applications such as fuel cells, batteries, photovoltaics and sensors. However, there have never been demonstrations of light emission from such hybrids with curved single-layer graphene. Here we employ a simple solution method to prepare emissive hybrid quantum dots consisting of a ZnO core wrapped in a shell of single-layer graphene, and use these quantum dots to make a white light-emitting diode. The intermediate consolidated metal oxide@graphene core@shell QD is a kind of newly developed material which will be appropriate for a functional layer acting as an electron transport layer with high mobility in the field of such as DSSC, photovoltaic devices, sensor, lithium ion batteries (LIBs), photodetector, photocatalyst, photoelectrochemical cell (PEC) and light emitting diode etc. |
