Summary: This study presents a single-component white light emitter based on all-inorganic perovskites, which has abundant energy states for self-trapped excitons and ultra-high photoluminescence efficiency, making it suitable for solid-state lighting applications. A complementary white light is achieved by controlling the dual emissions of blue and yellow colors in a Cs2SnCl6:La3+ microcrystal. The effects of La3+ doping on the electronic structure and photophysical properties are investigated using density functional theory calculations and experimental results, providing insights into defect chemistry in heterovalent ions doped perovskite luminescent crystals.

Summary: Searching for efficient Mn4+ red phosphors for white lighting and display backlighting has attracted great attention. In this work, an efficient Mn4+-doped fluoroscandate, Rb2KScF6:Mn4+, with short fluorescence lifetime was prepared using a simple co-precipitation method. The nonequivalent occupation of Mn4+ for Sc3+ led to sharp red emissions, enhanced zero-phonon line, high quantum efficiency, and short fluorescence lifetime under blue light excitation. By coating the red Rb2KScF6:Mn4+ phosphor with yellow Y3Al5O12:Ce3+ or green beta-SiAlON:Eu2+ phosphor in various white light-emitting diodes, good optical parameters such as high color rendering index, low correlated color temperature, and acceptable color gamut were achieved, demonstrating its potential for white light illumination and backlight display applications.

Summary: In this study, a new hierarchical assembly strategy is proposed for the rational and precise construction of complex single-crystal superstructures. Unprecedented superclusters in Rubik's cube form are formed by aggregating oxohalide clusters as secondary building units. These Rubik's cubes then act as isolable tertiary building units to assemble diverse single-crystal superstructures. The captured intermediate assembly states provide a profound understanding of the assembly process at the atomic level.

Summary: This study investigates the influence of carbon-based negative electrode materials in flexible lithium-ion batteries (LIBs). Due to the strong intercalation ability of Li+, the initial columbic efficiencies (ICEs) of carbon-based negative electrode materials are low. By utilizing electrostatic potential, inorganic lithium salts, and graphene oxide (GO) with opposite zeta potential in ethanol, successful prelithiation of GO-based SnTiS3 anodes is achieved. Prelithiated GO matrix with enlarged layer distance improves ion conductivity and suppresses Li consumption. As a result, prelithiated free-standing membranes as negative electrodes for LIBs demonstrate significantly improved ICEs and capacity utilization. This strategy provides new insights for high-performance flexible wearable energy storage devices with prelithiated free-standing electrodes.

Summary: Sr-90 is a dangerous artificial radionuclide that is difficult to remove from complex aqueous environments. This study focused on the efficient removal of Sr2+ ions using potassium phosphatoantimonate (1D-K2SbPO6), which showed excellent adsorption capacity and selectivity for Sr2+ ions. The mechanism of Sr2+ removal was found to be ion exchange between Sr2+ and easily exchangeable K+ ions in K2SbPO6. This work provides a potential solution for radionuclide remediation using antimonate(V)-based ion exchange materials.

Summary: Zero-dimensional (0D) metal halides based on environmental friendliness, low cost, and earth-abundant elements have gained attention for various applications. In this study, Mn-doped 0D C4H12N2ZnX4 (X = Cl and Br) with strong green emission was developed for scintillator and white light-emitting diode (WLED) applications. Mn doping effect on the electronic structure of C4H12N2ZnX4 was investigated using spectroscopic studies and density functional theory (DFT) calculations. The results showed that Mn doping reduced the bandgap and enhanced the Mn d-d emission, resulting in high photoluminescence quantum yield (PLQY) and luminous efficacy in Mn-doped C4H12N2ZnX4-based WLEDs.

Summary: Two isostructural supertetrahedral T3 cluster-based chalcogenide compounds were synthesized using an ionic liquid-assisted precursor technique. It was found that the highly-dispersed In-Se cluster exhibited approximately 5 times higher photocatalytic H-2 evolution activity than that of the solid-state under visible light irradiation. On the other hand, the photocatalytic performance of the highly-dispersed In-S cluster was only slightly higher than that of the solid state due to its inferior visible-light absorption capability.

Summary: In this study, a new class of second-order nonlinear optical (NLO) crystals, non-pi-conjugated piperazine (H10C4N2, PIP) metal halides, represented by two centimeter-sized, noncentrosymmetric organic-inorganic metal halides (OIMHs) have been identified. H12C4N2CdI4, the first OIMH prepared, exhibits poor NLO performance due to its structure containing a CdI4 tetrahedron. However, by replacing CdI4 with a highly polarizable CdNI3 tetrahedron to obtain H11C4N2CdI3, a significant enhancement in NLO performance is achieved.
