来源：ACS PublicationsConventional approaches to light–matter interactions rely on engineering photonic density of states. More recently, tailoring the spatial geometry of atoms or emitters themselves has emerged as a powerful and complementary route to control collective radiative properties. Here, we experimentally realize a geometry-engineered ensemble of rare-earth ions by fabricating a periodic array of subwavelength gold nanoholes on lithium niobate implanted with thulium ions, forming a semi-two-dimensional array of quantum emitters embedded in a high-index crystalline thin film. The hybri...

来源：ACS PublicationsRhabdophane (REPO4·H2O; RE = La to Dy) and churchite (RE′PO4·2H2O; RE′ = Gd to Lu and Y) are secondary minerals formed via hydrothermal alteration of primary rare-earth minerals such as monazite (REPO4; RE = La to Gd) and xenotime (RE′PO4; RE′ = Tb to Lu and Y). Monazite and xenotime are promising host matrices for actinide-rich nuclear wastes. However, the aqueous alteration of these materials could result in the precipitation of rhabdophane and churchite. In this scenario, the actinides could partition into the secondary phases, and the subsequent α-decay of acti...

来源：ACS PublicationsRare-earth (RE) bis(trimethylsilyl)amide ({N(SiMe3)2}−, N″) chemistry is well-developed, whereas RE bis(trimethylsilyl)phosphide {P(SiMe3)2}− (P″) chemistry is immature. Here, we report a convenient protonolysis route to dimeric RE P″ complexes [RE(P″)2(μ-P″)]2 (1-RE; RE = Y, Gd, Dy, Er) from parent [RE(CH2C6H4-o-NMe2)3] and excess HP″. The reactions of 1-RE with THF gave the monomeric RE P″ complexes [RE(P″)3(THF)2] (2-RE; RE = Y, Gd, Dy, Er), and treatment of 1-RE with 2 eq. of KP″ gave the RE “ate” coordination polymers [RE(P″)2(μ-P″)2K]∞ (3-RE; Y, Gd, Dy, Er). Complexes ...

来源：ACS PublicationsRare earths play an irreplaceable role in high-tech fields as key strategic resources. It is of importance to achieve efficient recovery of rare earth elements. During the in situ leaching process, the already leached rare earth ions are reverse-adsorbed to low-grade ore layers, which seriously restrict the rare earth leaching efficiency. To explore the reverse adsorption behaviors and characteristics of rare earths in low-grade ore layers, this paper used low-grade ore as the adsorbent and systematically studied the reverse adsorption behaviors of La3+, Y3+, and Dy3+. The r...
