“…Recent progress in nanotechnology has provided a variety of nanomaterials from 0D nanoparticles or nanodots and 1D nanowires or nanotubes to 2D nanosheets. The former two have been intensively studied since the 1990s as quantum dots and wires, 1 while studies on 2D nanomaterials started more recently. For example, although unique physics was predicted in graphene nanosheets more than sixty years ago, it was not experimentally confirmed until the 2000s, 2 which was ten years later than the discovery of 0D fullerenes 3 and 1D carbon nanotubes.…”

Tantalum oxide (TaO 3 ) nanosheets coated on the surface of a LiCoO 2 cathode decrease its interfacial resistance in a solid-state battery by two orders of magnitude. Since the interfacial resistance is ratedetermining in the solid-state system, the interfacial structure of the nanosheet is anticipated to pave the way for realising high-performance solid-state lithium batteries. The reduction in the interfacial resistance also strongly suggests that the TaO 3 nanosheet is a self-standing solid electrolyte layer with an ultimate thinness of 1 nm. It has a wide band gap and a mesh structure with openings that are almost the same in size as the lithium ion, which prevents electronic conduction and allows the penetration of lithium ions, respectively.

“…The calculated band gap of the ZnO QDs in this work is larger than that of bulk ZnO (3.37 eV), 32 which agrees with that the band gap increases with decreasing the fluster size of semiconductor materials. 33 The PL spectra of ZnO QDs, PANI film, ZnO-PANI nanocomposite film and sandwiched PANI-ZnO-PANI-EB nanocomposite film (sample 6 as an example) under the excitation of 360 nm are shown in Figure 6. A weak emission peak at $ 417 nm has been observed for the PANI film, which is similar to that in the previous report that the emission peak was observed at 409 nm for the PANI solution of the leucoemeraldine base state in NMP under the excitation of 300 nm.…”

Controllable synthesis of novel sandwiched polyaniline (PANI)/ZnO/PANI free‐standing nanocomposite films is reported via spin coating of ZnO quantum‐dot interlayer on PANI base layer and then PANI surface layer on the ZnO interlayer. The thickness of the ZnO interlayer and the PANI surface layer can be easily controlled by adjusting spin time and spin speed, respectively. The effects of the ZnO interlayer thickness and the PANI surface layer thickness are examined in detail on the photoluminescence (PL) property. It is worth noting that coverage of the PANI surface layer on the ZnO interlayer can not only lead to great enhancement in the PL property but also to a maximum PL intensity at a medium PANI surface layer thickness. This maximum PL property is caused by the combined ZnO/PANI carrier transportation and PANI shielding effects. In addition, the nanocomposite films show reasonably good conductivity. © 2012 Wiley Periodicals, Inc. J Polym Sci Part A: Polym Chem, 2012

“…Such a behavior is a direct consequence of the spatial connement of charge carriers in the SC crystal and it is generally referred to as "quantum size effect". [22][23][24] In a rst approximation, the structure of colloidal luminescent SC nanocrystals, known as quantum dots (QDs), can be separated in 2 regions: the core (bulk phase) and its outer surface. Since such nano-objects exhibit a very large surface-to-volume ratio, the surface state energy levels related to the surface atoms differ from the bandgaps of the cores.…”
