来源：ACS PublicationsRare-earth ion (Pr3+, Nd3+, and Tm3+)-doped yttrium vanadate (YVO4) crystals have aroused great research interest owing to their excellent laser performances. However, the microstructures, which underlie the optical properties of these crystals, are still unclear. In this paper, the stable crystal structures of the YVO4:Re (Re = Pr, Nd, and Tm) systems are predicted by using the crystal structure analysis by the particle swarm optimization (CALYPSO) structure search method. The unique tetragonal structures with the P4̅m2 (no. 115) space group for the YVO4:Re crystals are ide...

Controlling Magnetic Anisotropy of Endohedral Lanthanide Ions by Carbene Addition Paramagnetic NMR, Lanthanide Luminescence, and Single-Molecule Magnetism in Adamantylidene Adducts of MSc2N@C80 (M = Nd, Dy)来源：ACS PublicationsMetallofullerenes with endohedral lanthanides have emerged as a versatile class of single-molecule magnets owing to strong single-ion magnetic anisotropy, which can be realized in the interior of the fullerene cage. Since exohedral chemical modification of fullerenes is often used to adjust their properties and processability for prospective practical applications, it is n...

Concentration-Quenching-Suppressed Eu3+-Activated Ba3Lu2B6O15 Orange-Red-Emitting Phosphors via One-Dimensional Structural Confinement for Thermally Stable White LEDs 来源：ACS PublicationsConventional Eu3+-activated phosphors often suffer from severe concentration quenching at high doping levels, significantly limiting their achievable brightness and efficiency. Furthermore, achieving both high color purity and strong emission intensity in the orange-red region remains challenging. In this context, we report the successful synthesis of Eu3+-activated Ba3Lu2B6O15 phosphors via a multistep so...
