来源：ACS PublicationsRare earth hexaborides (REB6) have attracted considerable attention owing to their unique structure. However, the ultrarigid boron cage covalent network within this structure poses immense challenges to the controlled synthesis of their nanocrystals, severely hindering the exploration of their electronic properties and promising application directions. Here we successfully synthesize monodisperse LaB6 nanocrystals with tunable sizes down to sub-20 nm, during which the formation of reactive intermediates and a solution chemistry-like reaction pathway facilitate the formation ...

Dual Self-Trapped Exciton and Rare-Earth Emissions from Sb3+/Pr3+-Activated Metal Halide toward Plant Cultivation Lighting, Dynamic Multilevel Anti-Counterfeiting, and High-CRI WLEDs 来源：ACS PublicationsSolid-state lighting technologies for protected horticulture and data security demand luminescent materials whose emission characteristics can be precisely engineered. Here, a novel lead-free double perovskite Cs2NaLuCl6:Sb3+,Pr3+ was synthesized via a hydrothermal route to supply the blue and red photons essential for plant photosynthesis. Incorporating Sb3+ (ns2 configuration) into the host la...

来源：ACS PublicationsIn this study, Ni-Co-Al mixed oxides were synthesized via continuous-flow hydrothermal synthesis (CFHS) in supercritical water (T ≥ 445 °C, p = 24 MPa) and combined with different loadings of La-, Ce-, and Ga-based oxides. From these precursors, catalysts for the decomposition of ammonia were generated through reductive pretreatment in hydrogen. The addition of Ga leads to less active catalysts that contain (Co,Ni)-Ga phases, which are transformed into (Co,Ni)4N during NH3 decomposition. In contrast, La- and Ce-based oxides strongly enhance the catalytic activity. The b...

来源：ACS PublicationsThree rare-earth-embedded phosphotungstates with a dimeric sandwich structure containing two types of building blocks (BBs) [NH2(CH3)2]11H[RE(P2W17O61)(W5O18H)]·9H2O [RE = Dy3+ (1), Er3+ (2), Pr3+ (3)] have been synthesized via a one-pot self-assembly strategy. A distinctive feature is that the polyanion [Dy(P2W17O61)(W5O18H)]12– was composed of one monolacunary Dawson [P2W17O61]10– and one monolacunary Lindqvist [W5O18]5– segments. To the best of our knowledge, this is the first successful synthesis of a rare-earth-embedded polyoxotungstate incorporating both Dawson-ty...
