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...

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...
