New routes to alkali-metal–rare-earth-metal sulfides

Europium chalcogenide magnetic semiconductor nanostructures

“…There are few alkali metal lanthanide sulfide phases reported, one of the rare examples, is the ternary with the composition ALnS 2 (A = alkali metal, Ln = lanthanide) [94]. What is interesting is that the NaEuS 2 reported exhibits the ␣-NaFeO 2 structure type, which has the same anion packing as the rock salt, but the cations are segregated into alternating layers.…”

Catalytic photodegradation of Congo red in aqueous solution by Ln(OH)3 (Ln = Nd, Sm, Eu, Gd, Tb, and Dy) nanorods

“…Along with the chemical composition and the crystal structure, shape and dimensionality are considered as very important factors that influence the properties of materials [7]. Rare earth based elements have 4f electrons, relatively large atomic magnetic moment, strong spin-orbit coupling characteristics, and therefore they show remarkable optical, electrical, and magnetic properties, with a broad application in many fields, such as high-quality phosphors [8], up-conversion materials [9] and catalysts [10,11]. Lanthanide hydroxides are typical one-dimensional nanomaterials.…”

Controllable Synthesis and Luminescence Properties of La(OH)3 and La(OH)3:Tb3+ Nanocrystals with Multiform Morphologies

“…[2,3,[20][21][22][23][24] If rare-earth compounds were fabricated in the form of a 1D nanostructure, they would be expected to be highly functionalized materials, acting as electrically, magnetically, or optically functional host materials as well. [15,[25][26][27] So far, there have been many reports about 1D lanthanide compounds obtained by various synthesis methods.…”
