来源：X-MOLPermanent magnets are the fundamental component in the development of modern technology, with their applications extending to fields such as energy generation, transportation, communication, and medical imaging etc. Even though rare-earth transition-metal (RE-TM) intermetallic perform well, rare-earth sources have recently become a bottleneck, and research is being conducted in a number of different ways. To address these gaps, it is essential to explore new approaches to design and manufacture the permanent magnets with non-rare earth materials or reduced content of rare earth element...

来源：ACS PublicationsRare earth halide solid state electrolytes (SSEs) have been attracting wide interest recently. However, the high cost of rare earth resources and poor cycling performance in all-solid-state batteries (ASSBs) hinder their practical applications. In this work, two novel high-entropy rare earth halide electrolytes, Li2.6(Y,Ho,Er,Tm,Yb)Cl5.6 (HEE-1) and Li2.6(Y,Ho,Er,Tm,Yb)0.5Zr0.5Cl6.1 (HEE-2), were rationally designed. Both electrolytes use five specially selected rare earth elements to achieve good cost effectiveness. These two electrolytes show high ionic conductivities of 0...

High-Quality Single-Source White-Light Emission in Double Perovskite Cs2NaGdCl6 Sb3+Tb3+Mn2+ for Ratiometric Optical Thermometry and Anti-Counterfeiting Applications 来源：ACS PublicationsIn lead-free halide double perovskites, doping and alloying are key strategies for optical performance enhancement. However, achieving stable full-spectrum white emission in single-component phosphors remains challenging. Herein, high-quality single-phase white emission is realized in Cs2NaGdCl6 via Sb3+/Tb3+/Mn2+ codoping. Pristine Cs2NaGdCl6 shows a weak sky-blue emission, while Sb3+ doping significantly ...

来源：ACS PublicationsA novel orthorhombic polymorph of (NH4,Li)Eu(MoO4)2 enabled by partial substitution of NH4 with Li was synthesized via a one-pot low-temperature hydrothermal route using a Li/NH4 precursor solution. Synchrotron X-ray powder diffraction and Rietveld refinement confirmed that this phase crystallizes in an orthorhombic lattice, representing a new structure type distinct from the known triclinic and tetragonal phases (P1 and I41/a space groups). Under UV excitation, the orthorhombic ((NH4)1–xLix)Eu(MoO4)2 (x = 0.074–0.172) with Pbcn space group exhibits intense red photoluminesc...
