Summary: Controllable synthesis of NH2-Ce-BDC with a second-order magic cube morphology was achieved via H+ mediation in nucleation and growth stages. The concentric diffusion field was identified as a key factor in the formation of magic cube-like structures. The derived CeO2 exhibited unique gullies and grooves, which facilitated the deposition of Pt nanoparticles. The interaction between Pt and mc-CeO2 in mc-Pt/CeO2 was stronger compared to c-Pt/CeO2 derived from cubic Ce-MOFs. Pt2+ ions, hydroxyl oxygen, and oxygen defects were found to contribute to the exemplary catalytic activity of mc-Pt/CeO2 towards HCHO oxidation.

Summary: ZnSe/ZnO heterostructures were synthesized using the microwave-assisted hydrothermal method with zinc acetate and zinc nitrate as the source of Zn2+ ions. The incorporation of ZnSe into the ZnO matrix resulted in changes in the size of ZnO crystallites and lattice parameters. Optical and texture analyses showed that ZnSe particles caused a decrease in gap energy and a significant increase in the specific surface area of ZnSe/ZnO heterostructures. ZnSe/ZnO heterostructures synthesized with zinc acetate exhibited better photocatalytic performance in visible light compared to pure ZnO.

Summary: This study prepared two-dimensional CdSe-PbSe heterostructures and PbSe NPLs through Pb2+-for-Cd2+ cation exchange and characterized the intermediary NCs with advanced microscopy and spectroscopy techniques. The growth of PbSe domains in CdSe NPLs occurs through the replacement of zinc blende CdSe lattice with rock salt PbSe phase while preserving the anion sublattice. Temperature-dependent emission measurements reveal size-dependent change of band gap energy and the influence of the anisotropic shape.

Summary: The size-dependence of thermally enhanced upconversion luminescence (UCL) for UCNPs has been previously considered to be monotonous. However, this study finds that the monotonic relationship between UCL thermo-enhancement ratio and particle size is broken when the size of UCNPs goes below 7 nm. The breaking of monotonicity is accompanied by a change in the relationship between luminescence properties and particle size and supports the explanation of UCL thermo-enhancement through lattice thermal expansion-induced alleviation of surface quenching.

Summary: In this paper, a novel technique for activating a long-lasting phosphor (LLP) via oxygen-vacancy-rich Ca2MgSi2O7:Eu2+ (V-O-CMSE) is proposed, which enhances the persistent luminescence of Eu2+. V-O-CMSE exhibits a long duration and high charge storage capacity, making it efficient for various applications. The intensity of V-O-CMSE is enhanced and can compensate for the flicker effect of AC-LEDs. A new approach for generating white light emission during dimming time is presented, and an AC-LED lamp with a flicker percentage drop of 29.9% is manufactured. Dynamic anti-counterfeiting applications are also demonstrated. These discoveries are likely to accelerate the development of new LLP materials.
