The two-dimensional-three-dimensional (2D-3D) heterostructured perovskite solar cells (PSCs) have drawn widespread interest, wherein the organic spacer plays a significant role in photovoltaic performance. Herein, novel π-conjugated with aggregation-induced emission (AIE) property, (Z)-2-([1,1'-biphenyl]-4-yl)-3-(5-(4-(3-aminopropoxy)phenyl)thiophen-2-yl)acrylonitrile (BPCSA-S), is designed and synthesized, which successfully applied for situ construction of 2D-3D PSCs via two-step solution...
CsPbX3 (X = Br, Cl, I) perovskite quantum dots (PQDs) are the rising star for various display applications owing to their excellent opto-electrical properties, such as an adjustable spectrum, narrow emission linewidth and high yield. However, these PQDs well known suffer from intrinsic instability under atmospheric conditions. In this work, a novel photosensitive ligand, phenylbis(2,4,6-trimethylbenzoyl)phosphine oxide (XBPO), was employed dual-functional reagent PQD surface engineering. The...
Hot-injection method is widely used in the synthesis of colloidal nanocrystals. The conventional hot-injection process suffers from severe yield loss mass production monodisperse time-consuming standard cooling procedure via long-distance thermal transport results continuous nanocrystal growth, leading to broad size distribution and loss. In this paper, we employed direct injection low-temperature solvent as an additional quenching agent. CsPbBr3 nanocrystals with highly efficient...
Zeolite A (LTA)-coated Mn-doped perovskite quantum dot CsPb1–xMnxCl3@LTA (x = 0, 0.2, 0.4, 0.6, and 0.8) composites were fabricated by vapor deposition crystallization. LTA not only improved the water, light, thermal stability of dots but also limited average size to less than 20 nm. Mn2+ doping exciton lifetime a matrix. The photogenerated carriers generated have decay life hundreds microseconds, which effectively improves photocatalytic efficiency. When x total yield CO CH4 was 1443.25...
CsPbX3 (X=Br, Cl, I) nanocrystals have broad application prospects, due to their high luminescent efficiency and low preparation cost. However, the stability of CsPbBr3 prepared using conventional methods is poor, so large-scale applications not yet been achieved. At present, most for improving involve inorganic or organic encapsulation. This makes it difficult them be applied devices that work with electrical injection. In this article, we report by solvent quenching method, without any...
All-inorganic halide perovskite quantum dots are widely known to suffer luminescence degradation owing their intrinsic instability in atmospheric circumstances. Their high surface energy and weak internal ionic bonding could result dot agglomeration structural degradation. In this work, we demonstrate that triallylamine is an efficient recovery agent reignite the emission of aged CsPbBr3 dots. The re-emit bright green light instantly after etching. X-ray photoelectron spectroscopy results...
