来源：ACS PublicationsPolaron formation has emerged as an important mechanism for unconventional luminescence in metal halide semiconductors. Here, we show that incomplete rare-earth-ion doping in the zero-dimensional hybrid halide (TMBA)2MnCl4 induces magnetic-polaron-mediated emission, rather than conventional local d-d or f-f transitions. Single-crystal structural analysis reveals that the compounds consist of isolated [MnCl4]2– tetrahedra separated by TMBA+ cations, forming a zero-dimensional framework. Upon rare-earth incorporation, Mn2+ ions retain tetrahedral coordination without the forma...

来源：ACS PublicationsSuperconductor/ferromagnet heterostructures have been investigated extensively because of their capability to break superconducting electron pairs. In this study, we report on heterostructures of a superconductor and heavy-fermion system as an alternative platform for a strong pair-breaking proximity effect. We fabricated rocksalt-type CeO/LaO heteroepitaxial bilayers, where LaO is a superconductor and CeO is a nonferromagnetic heavy-fermion system. While LaO(9.5–21 nm) thin films showed superconductivity below 4.4–5.2 K, the CeO(4.8–5.8 nm)/LaO(9.2–17 nm) bilayers showed no...

Determination of Solubility, Supersolubility, and Metastable Zone Width of Li2CO3 in the LiCl–CaCl2–NdCl3–PrCl3–FeCl3 Solution Environment from 293.15 to 363.15 K来源：ACS PublicationsThe turbidity technology was employed to determine the solubility, supersolubility, and metastable zone width of Li2CO3 in the mixed solution of the LiCl–CaCl2–NdCl3–PrCl3–FeCl3 environment over a temperature span from 293.15 to 363.15 K. The experimental data show that the solubility, supersolubility, and metastable zone width of Li2CO3 in a LiCl solution are mainly affected by temperature and concentration of LiCl...

Experimental and Density Functional Theory Study of the Structural, Optical, and Electronic Properties of La2NiMnO6 and Nd2NiMnO6 Double Perovskite Ceramics来源：ACS PublicationsDespite extensive study of La2NiMnO6 double perovskites, a systematic understanding of the effects of A-site rare-earth substitution on coupled structural, electronic, and optical properties remains lacking. Here, we provide the first integrated experimental-computational comparison of La2NiMnO6 (LaNMO) and Nd2NiMnO6 (NdNMO), establishing quantitative structure–property relationships. Rietveld refinement demonstrates that...
