Concentration-Quenching-Suppressed Eu3+-Activated Ba3Lu2B6O15 Orange-Red-Emitting Phosphors via One-Dimensional Structural Confinement for Thermally Stable White LEDs 来源：ACS PublicationsConventional Eu3+-activated phosphors often suffer from severe concentration quenching at high doping levels, significantly limiting their achievable brightness and efficiency. Furthermore, achieving both high color purity and strong emission intensity in the orange-red region remains challenging. In this context, we report the successful synthesis of Eu3+-activated Ba3Lu2B6O15 phosphors via a multistep so...

Modulating Electrochemical Performance of La2FeNiO6/MWCNT Nanocomposites for Hydrogen Storage Inquiries: Schiff-Base Ligand-Assisted Synthesis and Characterization来源：ACS PublicationsSince the role of the energetic active materials as cores of energy storage devices is still controversial, the verification and validation of multidimensional compounds with enriched “redox”, “physisorption”, and “spillover” pathways open new implications for the cycling stability and hydrogen storage mechanism. In this study, we investigate the structural–electrochemical contributions of double-perovskite La2FeNi...

来源：ACS PublicationsThe reaction of [LnIII(OArP-κ2O,P)3] (1-Ln, Ln = La, Sm, Y, Yb, and ArPO– = 2,4-tBu2-6-(Ph2P)C6H2O–) with the copper(I) triflate toluene adduct yields the corresponding dinuclear rare-earth metal(III)–copper(I) complexes [LnIII(OTf)(μ-OArP-1κ1O,2κ1P)3CuI] (2-Ln, Ln = La, Sm, Y, Yb) in clean conversion. In order to explore an alternative synthetic route by starting from a mononuclear copper complex instead of a rare-earth metal complex, the mononuclear copper complex [(HOArP-κP)3CuIOTf] (3) was prepared from copper(I) triflate toluene adduct and HOArP. However, the reaction o...

来源：ACS PublicationsMalonate ligands demonstrate versatility for intercalating metal complexes into layered rare-earth hydroxides (LREHs), enabling controlled tuning of coordination geometry and composition. As a proof of concept, a series of copper(II) malonate complexes with various substituents was synthesized and successfully intercalated into layered yttrium, europium, or terbium hydroxide at room temperature via anion-exchange reactions. The copper content in these hybrid materials increased in the order: butylmalonate
