Abstract: The photoluminescence quenching of the Rhodamine 6G molecules deposited on fluorinated, thiophenol-functionalized, and 4-nitrophenyl-functionalized graphene layers were studied. Both the spectroscopic measurements and the atomic force microscopy imaging confirmed that Rhodamine 6G molecules are present on graphene, functionalized graphene and the bare substrate. The Raman signals of the molecules are enhanced for all the probed functionalized graphene samples. On the other hand, the photoluminescence from the Rhodamine 6G is suppressed when the molecules are in contact with a graphene layer for all types of probed functionalized graphene. The large Raman maps measured on the tested samples showed that the quenching of the photoluminescence is not significantly affected by the local environment.

TL;DR: In this paper, the properties of nano-carbon based materials are discussed in relation to the electrical and thermal conductivities of various nano carbon based materials, and the similarities and differences observed in the transport properties of an isolated single layer graphene out of the bulk (SLG), or a few layers of graphene out-of-the bulk (FLG), supported or suspended, and those of a single (stage-1) or more (stage n, where n=2,3,…) of these carbon layer planes sandwiched between planes formed by other chemical species, as is

TL;DR: In this paper, the Curie-Weiss temperature of superlattices with odd ξ numbers was shown to be equal to the bulk phase Neel temperature, while negative θ was shown for even ξ.

TL;DR: In this article, a turning point appeared to occur when the number of women reached a critical mass of about 10-15% of the students in a class at MIT, where women participated more and more in class discussions.
