TL;DR: A new type and high density of surface state of GQDs arises, leading to high yields (more than 70 %) and excitation-independent emission and FLQY = fluorescence quantum yield.

TL;DR: Graphene-based planar micro-supercapacitors are layer-by-layer printed on flexible substrates using micro-extrusion technique as discussed by the authors, where laminated graphene films and polyvinyl alcohol-H 2 SO 4 gel serve as the interdigitated micro-electrodes and electrolyte, respectively.

TL;DR: In this paper, a series of single-phase CaWO4:Dy3+ phosphors have been prepared via a conventional solid state reaction process, and X-Ray diffraction (XRD), scanning electron microscopy (SEM), high-resolution transmission electron microscope (HRTEM), photoluminescence (PL), and fluorescent decay curves were used to characterize the synthesized samples.

TL;DR: Submicrometer-sized hollow TiO(2) spheres are directly self-assembled from TiO (2) nanoparticles without using any template or surfactant as a scattering layer for dye-sensitized solar cells, showing good visible light scattering match to significantly improve the photoconversion efficiency.

TL;DR: A template-free strategy is exploited to bottom-up synthesize yolk-shell vanadium oxide through a two-step spontaneous assembly of hydrolytically formed subunits in a one-pot process that exhibits excellent cathode performance for lithium ion batteries.
