One-dimensional nanosized phosphors demonstrate special structural and photoluminescence properties, which have application potential in some optical fields. In this article, we present our recent progress on preparation and luminescence properties of some one-dimensional rare earth compounds and complexes, the core–shell oxide nanowires prepared by a two-step hydrothermal route, the nanowires of some inorganic compounds doped with rare earths and rare earth complexes/PVP composites prepared by the electrospinning method, and the rare earth complexes in the SBA-15 mesoporous molecule sieves. In these systems, some novel or improved photoluminescence properties are observed such as improved luminescence quantum yield, thermal stability and/or photostability, and depressed thermal effect in upconversion luminescence.

Three isotypic rare earth complexes,catena-poly[[aquabis(but-2-enoato-κ2O,O′)yttrium(III)]-bis(μ-but-2-enoato)-κ3O,O′:O;κ3O:O,O′-[aquabis(but-2-enoato-κ2O,O′)yttrium(III)]-μ-4,4′-(ethane-1,2-diyl)dipyridine-κ2N:N′], [Y2(C4H5O2)6(C12H12N2)(H2O)2], the gadolinium(III) analogue, [Gd2(C4H5O2)6(C12H12N2)(H2O)2], and the gadolinium(III) analogue with a 4,4′-(ethene-1,2-diyl)dipyridine bridging ligand, [Gd2(C4H5O2)6(C12H10N2)(H2O)2], are one-dimensional coordination polymers made up of centrosymmetric dinuclear [M(but-2-enoato)3(H2O)]2units (M= rare earth), further bridged by centrosymmetric 4,4′-(ethane-1,2-diyl)dipyridine or 4,4′-(ethene-1,2-diyl)dipyridine spacers into sets of chains parallel to the [20\overline{1}] direction. There are intra-chain and inter-chain hydrogen bonds in the structures, the former providing cohesion of the linear arrays and the latter promoting the formation of broad planes parallel to (010).

A facile water-bath pretreated hydrothermal route is developed for ultralong Ca2B2O5·H2O nanowires (length: <230 μm) as a promising photoluminescent host candidate.
