The easily tunable emission of halide perovskite nanocrystals throughout the visible spectrum makes them an extremely promising material for light-emitting applications. Whereas high quantum yields and long-term colloidal stability have already been achieved emitting in red green spectral range, blue region currently lags behind, with low yields, broad profiles insufficient stability. In this work, we present a facile synthetic approach obtaining two-dimensional CsPbBr3 nanoplatelets...
The photoreduction of CO2 on inorganic semiconductors has been researched for several decades, but the conversion efficiency is still low due to recombination photo-generated electron–hole pairs, utilization solar energy and weak adsorption CO2. Here we first time demonstrate that metal–organic frameworks such as ZIF-8 can effectively adsorb dissolved in water, promote photocatalytic activity a semiconductor catalyst reduction into liquid fuels an aqueous medium. In particular, Zn2GeO4/ZIF-8...
The colloidal synthesis and assembly of semiconductor nanowires continues to attract a great deal interest. Herein, we describe the single-step ligand-mediated single-crystalline CsPbBr3 perovskite (NWs) directly from precursor powders. Studies reaction process morphological evolution revealed that initially formed nanocubes are transformed into NWs through an oriented-attachment mechanism. optical properties can be tuned across entire visible range by varying halide (Cl, Br, I) composition...

Here, one‐pot synthesis CsPbBr 3 perovskite supercrystals (SCs) in colloidal dispersion by ultrasonication is reported. The growth SCs occurs through spontaneous self‐assembly individual nanocrystals (NCs), which form highly concentrated solutions precursor powders....

Theoretical predictions imply these N carbonaceous much favorable storing lithium...

Post-synthetic shape-transformation processes provide access to colloidal nanocrystal morphologies that are unattainable by direct synthetic routes. Herein, we report our finding about the ligand-induced fragmentation of CsPbBr3 perovskite nanowires (NWs) into low aspect-ratio CsPbX3 (X=Cl, Br and I) nanorods (NRs) during halide ion exchange reaction with PbX2 -ligand solution. The shape transformation NWs-to-NRs resulted in an increase photoluminescence efficiency owing a decrease...
The performance of tin halide perovskite solar cells (PSCs) has been severely limited by the rapid crystallization perovskites, which usually leads to an undesirable film quality. In this work, we tackle issue regulating nucleation and crystal growth films using a small Lewis base additive, urea. urea–SnI2 interaction facilitates formation larger more uniform clusters, thus accelerating process. Additionally, process is extended, resulting in high-quality with compact morphology, increased...
