来源：ACS PublicationsThree phases of stoichiometric europium(III) iodate compounds are probed as candidates for optical quantum memory to determine the impact of reaction conditions on phase formation and to relate crystal structure to their ability to host persistent excited states relevant to quantum memory. Hydrothermal synthesis procedures for growing macroscopic single crystals of rectangular-block α-Eu(IO3)3 (P21/c), yellow hexagonal plate β-Eu(IO3)3 (P21/n), and transparent plate NaEu(IO3)4 (Cc) are presented. The ability to burn narrow and long-lived spectral holes on the 7F0 → 5D0 optic...

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, ...
