来源：ACS PublicationsMagneto-optical crystals play a decisive role in the performance of optical isolators in fields such as optical fiber communication and laser sensing. However, conventional materials are often limited by inadequate temperature stability and high optical loss. To overcome these challenges, a novel Ce/Sc-codoped europium iron garnet crystal (CexEu3–x–zCazScyFe5–yO12) was designed and successfully grown using an optimized edge-defined film-fed growth method. This work systematically elucidates the synergistic effect of codoping on the crystal structure and magneto-optical prope...

来源：ACS PublicationsThe exploration of Nd and Eu precursors bearing the (form-)amidinate ligand for atomic layer deposition (ALD) with water resulted in crystalline Nd2O3 and Eu2O3 thin films on Si substrates at low temperatures. Eu2O3 films exhibit strong photoluminescence with well-defined 5D0 → 7Fj transitions that evolve from surface-dominated to bulk-like emission as thickness increases, approaching the optical quality of single crystals. In contrast, Nd2O3 shows temperature-dependent visible emission from defect states rather than f–f transitions, while controlled nitrogen incorporation a...

来源：ACS PublicationsStoichiometric materials of Eu(III) offer a promising platform for quantum memories attributable to their unique capability to display a distinctive, nondegenerate 5D0 → 7F0 transition, which enables precise mapping of optical quantum states into their energy-level manifold─a prerequisite for reliable storage and retrieval on demand. However, placing Eu(III) into chiral polar structures, which are necessary for achieving narrow spectral line widths and long optical lifetimes, is a daunting task. Here, we discover Eu2(SeO3)2(SO4)(H2O)2, a rare Eu(III) material that exhibits c...

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...
