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...

A Mixed-Anion Design Approach for High-Efficiency X-ray Scintillators A Study of KLn(SO4)F2 (Ln = Eu, Gd, Tb, Dy, Ho, and Tm) 来源：ACS PublicationsHigh-quality single crystals of mixed anion rare earth sulfate fluorides KLn(SO4)F2 (Ln = Eu, Gd, Tb, Dy, Ho, and Tm), monoclinic space group P21/m, were obtained using an HF-free mild hydrothermal synthesis. Thermal, magnetic, and optical properties of these materials were investigated after determining their crystal structures and their chemical compositions using a combination of single-crystal and powder X-ray diffraction. Notably, the photol...
