Trivalent rare-earth ions (RE3+) exhibit sharp 4f–4f transitions that are highly sensitive to dipole–dipole interactions (DDIs), yet the intrinsic short-range of DDIs restricts their application in long-distance quantum coupling. Here, we demonstrate a plasmonic nanocavity pair that simultaneously couples to upconversion nanoparticles (UCNPs) and quantum dots (QDs), enabling enhanced emission and inter-emitter interaction. The combined effects of Purcell enhancement and surface plasmon polariton (SPP) propagation extend the DDI-mediated energy transfer over a record distance exceeding 7.5 μm, ...

来源：ACS PublicationsTo better understand the interactions of rare earth elements (REE) with anaerobic microorganisms, we explored the proteome response of a Clostridium strain to europium (Eu) and its adjacent lanthanide, samarium (Sm), comparing them with the well-studied metals iron, calcium, and zinc. Our findings showed that Eu and Sm induced a number of proteomic changes consistent with Fe, Ca, and Zn, but Eu enhanced expression for ATP synthase and electron transfer flavoproteins, while Sm increased expression of proteins associated with butyric acid metabolism. In contrast, Fe reduced AT...

来源：ACS PublicationsThe development of high-performance deep-ultraviolet (deep-UV) second-order nonlinear optical (NLO) crystals that simultaneously combine noncentrosymmetric crystal structure, broad transparency, strong second-harmonic generation (SHG) activity, and high thermal and chemical stability remains a formidable challenge due to intrinsic trade-offs among these properties. Herein, we present a multicomponent structural design strategy that enables the rational synthesis of a new KBe2BO3F2 (KBBF)-like rubidium lanthanum sulfate, RbLa(SO4)2. In this crystal, the highly polarizable [La...

来源：ACS PublicationsRare-earth (RE) chalcogenides have been extensively studied as infrared nonlinear optical (NLO) materials and have become promising candidates for achieving good integrated performance; however, the subgroup RE chalcophosphates have been rarely studied, especially Y-based ones. Here, a new quaternary RE selenophosphate, Cs2YP2Se7 (1), and the first NLO-active Y-based selenophosphate, KYP2Se6 (2), were synthesized via the reactive flux AI (A = K, Cs) assisted RExOy–B–Se solid state method developed by us. They crystallize in the monoclinic P21/n and orthorhombic chiral P21212...
