PbS QDs, other chalcogenides QDs, as well as emerging two-dimensional QDs, are further accounted through multiple methods, such as bilayer architectures, core-shell structures or blending multiple QDs into perovskite layers. In the end, an outlook perspective of this field has been proposed to ...
Metal halide perovskites can be readily synthesized, they exhibit tunable physical properties and excellent performance, and they are heavily studied optoelectronic materials. Compared to the typical three-dimensional perovskites, morphological-level one
areal capacitance of 2.94 F cm−2 at the current density of 4 mA cm−2, which was higher than those of the single-shelled ones (1216 F g−1), core–shell ones (943 F g−1), solid ones (664 F g−1), and the bulk material (306 F g−1) (Fig...
Keywords: lead-free; metal-halide double perovskites; optoelectronic properties; photovoltaics; stability 1 Introduction Organic–inorganic halide perovskite solar cells have witnessed remarkable progress in the past few years with a rapid surge in the power conversion efficiency (PCE) from 3.8% in 2009...
Fig. 8. A halide perovskites-based photocatalysts with Z-scheme is made by CsPbBr3 nanocrystals on a core/shell nanorod array of amine-functionalized reduced graphene oxide-coated α-Fe2O3. Due to the timely separated photo-generated electrons and holes with substantial redox capacity exhibit sign...
. The slightly higher length is attributed to nanoparticles packing and the oscillating pattern alternates between characteristic ions for silver (such as Ag+,109Ag+and Ag2+) and PVP (such as C4H6NO+and C6H10NO+). We interpret that this is related to the core–shell structure of AgNPs/PVP...
Similarly, SHG was also enhanced in 1L-MoS2 by coupling it to the core (Au) shell (SiO2) monomer and dimers [105]. Furthermore, the plasmonic metasurfaces are used to modulate the valley-selective SHG from the 1L-TMDs spatially. For example, Spreyer et al. [110] investigated the ...
