来源：ACS PublicationsIn summary, This work has demonstrated, for the first time, that SALI is a viable approach to open pores and gain access to OMS in RE-cluster-based MOFs. We have used Y-CU-45 as a platform for these studies, as this MOF has unique 6-connected RE6-cluster nodes, with 6 coordinatively unsaturated sites that are capped by modulators from the synthesis of this MOF, partially blocking its pores. Seven different ligands were tested for SALI experiments, and it was observed that their intrinsic acidities are critical to promoting the displacement of the original capping ligands on ...

来源：ACS PublicationsRare earth elements (REEs) are essential to modern technologies yet are typically sourced from regolith clays containing cation-exchanging minerals such as kaolinite, and conventional extraction methods often rely on environmentally harmful organic solvents. Deep eutectic solvents (DESs) provide a more sustainable alternative due to their tunable solvation properties, low volatility, and high thermal stability. Kaolinite contributes nanoscale features that enhance its suitability for REE separations, including its layered morphology featuring nanometer-scale layer thickness,...

来源：ACS PublicationsIn recent years, hybrid rare-earth double perovskites (HREDPs) have garnered interest, owing to their significant optical properties. However, we will combine optical properties and other physical properties to promote the functional diversity of materials, so we report the successful synthesis of an HREDP, (HQ)4KTb(NO3)8 (1, HQ = quinuclidine cation), and investigate the structure–property relationships underlying its multifunctional characteristics. Differential scanning calorimetry (DSC) reveals two pairs of characteristic peaks at 262/288 K upon heating and at 254/282 K ...

来源：ACS Publications(Co)doping luminescent center(s) in a host is a universal strategy to photoluminescence (PL) modulations for extensive applications, yet its mechanism and interactions between structure and behavior in many phosphors remain ambiguous. Herein, via a facile sol–gel reaction method, differently tendentious occupations of Ce3+ in distinct crystallographic sites of K3YSi2O7 (KYS) lead to tunable PL in between blue and bluish-green under diverse excitations with high quantum efficiency. The generation of wide trap energy levels originating from heterovalent substitution Tb3+ → K+ ...
