Fluorinated graphene quantum dots (F-GQDs) were synthesized by cutting fluorinated through a hydrothermal approach. The F-GQDs with oxygen-rich functional groups have F/C atomic ratio of ca. 23.68% and diameter 1-7 nm. photoluminescence (PL) properties the investigated. results showed that besides exhibiting bright blue PL, display clear upconversion PL.
Abstract The long spin diffusion length makes graphene very attractive for novel spintronic devices and thus has triggered a quest integrating the charge degrees of freedom. However, ideal is intrinsic non-magnetic, due to delocalized π bonding network. Therefore, synthesis ferromagnetic or its derivatives with high magnetization urgent both fundamental technological importance. Here we report that N-doping can be an effective route obtain ca. 1.66 emu/g make oxide (GO) ferromagnetism...
Fluorination was confirmed to be the most effective route introduce localized spins in graphene. However, adatoms clustering perfect graphene lead a low efficiency. In this study, we report experimental evidence of generation spin magnetic moments on defective (reduced oxide) through fluorination. More interstingly, result shows that defects help increase efficiency fluorination with regard density created. Fluorinated reduced oxide can have high moment 3.187 × 10–3 μB per carbon atom and...
Highly oxidative debris (OD) was obtained by aqueous ammonia wash of as-prepared graphene oxide (GO) which composed OD and lightly GO sheets. The magnetic properties were studied. results showed that has a low magnetization 0.16 emu/g, the can be increased from 0.38 to 0.42 emu/g discarding low-magnetization OD. Thus, this study provided reliable method increase GO. Hydroxyl groups proposed source.
For Si anode materials used for lithium ion batteries (LIBs), developing an effective solution to overcome their drawbacks of large volume change and poor electronic conductivity is highly desirable. Here, the composites ZnO-incorporated carbon-coated silicon/porous-carbon nanofibers (ZnO-Si@C-PCNFs) are designed synthesized via a traditional electrospinning method. The prepared ZnO-Si@C-PCNFs can obviously these two provide excellent LIB performance with rate capability stable long cycling...

The experimental approach involves utilization various techniques, namely ash fusion temperature (AFT) tests, X-ray fluorescence spectroscopy, diffraction (XRD), scanning electron microscopy (SEM), differential thermal analysis (DSC),...
Reduced graphene oxide quantum dots (rGOQDs) were synthesized by annealing GOQDs in H2 atmosphere. The photoluminescence (PL) properties of and the rGOQDs samples investigated. results showed that compared to GOQDs, a blue purple tunable PL can be obtained regulating temperature. increase fraction newly formed isolated sp2 clusters may responsible for observed PL.
Nitrogen-doped graphene oxide (NGO) was synthesized by irradiation of (GO) in NH3 atmosphere. NGO obtained GO for 10 min has high N content 13.62 at. %. The photoluminescence (PL) properties were investigated. results showed that compared with GO, exhibits significant PL enhancement a ratio approximately 1501.57%. It may attribute to the amino-like N, which can effectively enhance because amino conjugation effect.
Rational engineering of nanostructured anode materials is important to develop lithium-ion batteries (LIBs). In this study, hierarchical composites fluoridated carbonaceous GeO2 (F-GeO2@C) with rich oxygen vacancies were prepared by a simple annealing method. It found that F– ions not only exist in the carbon matrix but also replace O2– metallic oxides. The abundant introduced can provide more active sites and contribute better electronic conductivity. Moreover, density functional theory...
