Traditional smart fluorescent materials, which have been attracting increasing interest for security protection, are usually visible under either ambient or UV light, making them adverse to the potential application of confidential information protection. Herein, we report an approach realize protection and storage based on conversion lead-based metal-organic frameworks (MOFs) luminescent perovskite nanocrystals (NCs).

Under illumination of light-emitting diode (LED) or sunlight, the green color all-inorganic CsPbBr3 perovskite nanocrystals (CPB-NCs) often quickly changes to yellow, followed by large photoluminescence (PL) loss. To figure out what is happening on CPB-NCs during change process, morphology, structure, and PL evolutions are systematically investigated varying influence factors illumination, moisture, oxygen, temperature. We find that yellow mainly originated from CPB crystals formed in...
Abstract Achieving good stability while maintaining excellent properties is one of the main challenges for enhancing competitiveness luminescent perovskite CsPbX 3 (X=Cl, Br, I) nanocrystals (NCs). Here, we propose a facile strategy to synthesize ceramic-like stable and highly CsPbBr NCs by encapsulating them into silica derived from molecular sieve templates at high temperature (600–900 o C). The obtained -SiO 2 powders not only show photoluminescence quantum yield (~71%), but also an...

The present polyolefin hydrogenolysis recycling cases acknowledge that zerovalent Ru exhibits high catalytic activity. A pivotal rationale behind this assertion lies in the propensity of majority species to undergo reduction within milieu. Nonetheless, suitability as an optimal structural configuration for accommodating multiple elementary reactions remains ambiguous. Here, we have constructed stable Ru0–Ruδ+ complex species, even under reaction conditions, through surface ligand engineering...

Hydrogels are ideal substrates for interfacial solar steam evaporation because of their tunable water enthalpy. However, conventional hydrogel-based evaporators suffer from severe shape-morphing and slow transportation dominated by osmotic hydration. Inspired the space-confined effect in plant cell walls, we propose to construct a 3D skeleton-supported hydrogel evaporator, which can develop against its shape deformation meshing bulk into many confined microspaces, resulting an interconnected...
