来源：ACS PublicationsSurface nanotopography plays a pivotal role in determining the physicochemical properties and nanobio interactions of nanomaterials. However, achieving precise control over such nanoscale surface architectures remains challenging, particularly for multifunctional rare-earth-based nanoparticles with diverse compositional and structural complexity. Here, we report a π–π conjugation-driven micelle inversion strategy for the versatile synthesis of rare-earth oxide nanoparticles featuring virus-like surface nanotopography and highly tunable compositions, including single-componen...

来源：ACS PublicationsThe optical performance of persistent phosphors like SrAl2O4:Eu2+,Dy3+ is limited due to environmental sensitivity. We fabricated a multifunctional phosphor–glass composite in which crystalline SrAl2O4:Eu2+,Dy3+ particles are embedded within a Sm3+-activated borotellurite glass matrix, enabling simultaneous stabilization of defect-mediated persistent luminescence and self-referenced optical thermometry. Structural and microscopic analyses confirm retention of phosphor crystallinity and homogeneous dispersion within the host. The composite exhibits dual-channel emission compo...

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...
