| 摘要: |
Free-standing optoelectronic graphene–CdS–gra-
phene oxide (G–CdS–GO) composite papers were prepared
by vacuum-assisted self-assembly. G–CdS hybrids were ？rst
prepared by a hydrothermal method and GO acts as a dis-
persant which makes it easier to disperse them to form
relatively stable aqueous suspensions for fabricating paper.
Transmission electron microscopy shows that CdS quantum
dots (QDs) with an average size of approximately 1–2 nm
were distributed uniformly on the graphene sheets. Photolu-
minescence measurements for the as-prepared G–CdS–GO
composite paper showed that the surface defect related emis-
sions of attached CdS QDs decrease and blue shift obviously
due to the change in particle size and the interaction of the
surface of the CdS QDs with both the GO and the graphene
sheets. The resulting paper holds great potential for applica-
tions in thin ？lm solar cells, sensors, diodes, and so on. |
