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 lat...

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...

来源：ACS PublicationsDiscovering sulfate optical crystals with enhanced birefringence and a broad transparency window is of great interest but remains challenging. Herein, two new rare-earth sulfate crystals NaNH4Y2(SO4)4 and NaKY2(SO4)4 were designed and successfully synthesized by introduction of rare-earth Y3+ ions into alkali metal sulfates. Transparent millimeter-sized single crystals were grown by a facile hydrothermal method, with NaNH4Y2(SO4)4 reaching dimensions up to 4 × 4 × 2 mm3. Both compounds are isostructural and built from identical structural units, namely [YO8] dodeca...
