The synergistic interaction of metal-dependent dye (N3) and N719 extends the absorptionvisible spectrumowing to the formation of intensive conjugation and intra-band charge transfer (Fig. 5b). Complex structure (N719 + N3) dyes exhibit a high EQE in the wavelength region of 470–700 nm on rGO...

The absorption spectrum of the Ag NMs wrapped by GO was then compared with that of bare NMs. As shown in Fig. 6c, besides the broad LSPR band of Ag NMs at 475 nm, new obvious peak at 230 nm appears, which is attributed to the π-π* electron transition of the C=O band35....
Graphene is a gapless two-dimensional (2D) material which exhibits an absorption spectrum from ultra-violet to terahertz wavelengths; it shows very large mobility and ambipolar characteristics19,20,21,22,23. Single-layer graphene absorbs only ~ 2.3% in visible and infrared regions and because...
Through a facile self-assembled process, an ultralight reduced graphene oxide/black phosphorus (rGO/BP) composite aerogel was successfully fabricated. The BP nanosheets were homogeneously distributed throughout the rGO 3D framework, and the interfaces between rGO and BP possessed four kinds of interconne...
UV-Visible Absorption Spectrum Bulk WS2 forms dark gray hexagonal crystals with a layered structure. They are not chemically active and can only be dissolved by a mixture of nitric and hydrofluoric acids. Each W(IV) center of WS2 is occupying a trigonal prismatic coordination sphere, which is ...
The appearance of characteristic rGO peak with slight shift together with the peaks of ZnO and SnO2 NPs in the UV absorption spectrum of rGO/ZnO/SnO2, clearly points towards the formation of the nanocomposite. 3.5. FTIR analysis The nature of bonding in the GO, mentha leaves extract, rGO, ...

Supramolecular chemistry offers an exciting opportunity to assemble materials with molecular precision. However, there remains an unmet need to turn molecular self-assembly into functional materials and devices. Harnessing the inherent properties of both disordered proteins and graphene oxide (GO), we repo...
In this paper, we introduce a nanocomposite as a humidity-sensitive sound absorber. The nanocomposites were prepared using hydrogel polymer (HP) as a matrix and graphene oxide (GO) as a filler. Results show that the surface energy of the nanocomposite is
