Pentagonal Bipyramidal Dy(III) Ions Bridged by Homologous Metallocyanate Anions into One-Dimensional Chain Structures Exhibiting Distinct Magnetic Relaxation Properties来源：ACS PublicationsThe continuously growing axially compressed pentagonal bipyramidal DyIII mononuclear structures exhibit excellent SIM properties. However, it is quite challenging to assemble these mononuclear fragments into a magnetic coupling system. Here we report a family of one-dimensional chain compounds, 1YFe, 2DyCr, 3DyFe, 4DyFe0.05Co0.95, and 5DyCo, composed of pentagonal bipyramidal rare earth (REIII) fragments bridg...

来源：ACS PublicationsUp to date, the development of highly efficient, visible light-active catalysts remains a formidable challenge due to the enhanced rising of atmospheric CO2 concentration. This study discusses a class of ceria-based high-entropy oxides designed to optimize charge carrier dynamics, surface reactivity, and CO2 activation efficiency. Due to the advantages of high configurational entropy and multi-element synergy, these materials achieved improved photocatalytic performance, surpassing conventional ceria-based systems. Structural and spectroscopic analyses reveal that Pr3+/Pr4+ ...

来源：ACS PublicationsAmong rare-earth ions, Dy3+ uniquely enables intrinsic white-light emission and is therefore considered a promising activator for solid-state lighting. However, its parity-forbidden 4f–4f transitions lead to intrinsically weak absorption and limited emission intensity. Ce3+ was identified as an efficient sensitizer in the host LiSrY2(BO3)3 (LSYB) to enhance Dy3+ emission through energy transfer. A series of Ce3+-singly doped, Dy3+-singly doped, and Ce3+/Dy3+ codoped phosphors were successfully synthesized via a high-temperature solid-state reaction. Under 347 nm excitation, ...

来源：ACS PublicationsThe heteroanionic rare-earth germanide oxide Sm26.25Ge22.75O5 was obtained by arc melting. The crystal structure determined by single-crystal X-ray diffraction (space group P4/nmm, a = 14.9838(2), c = 10.5353(1) Å) features [Sm6O] octahedra and capped [Sm8Ge] prisms that are condensed to Sm30Ge4O5 superclusters. These clusters form an interpenetrating framework with polyanionic Ge chains. Chemical bonding analysis reveals the substantial role of oxygen in stabilizing the structure: in the hypothetical oxygen-free compound, significant electron localization appears at th...
