Perovskite solar cells (PSCs) are emerging and promising alternatives to the market-leading solar cells due to their high performance, low fabrication cost, and versatile material modification.

The composition and microstructure control of Sm₂Fe₁₇N₃ powders lays the foundation for the enhancement of magnetic properties, which is mainly ascribed to the optimization of the intrinsic magnetic properties and domain structure.

A remarkable thermally-robust and stable metal–organic framework with lanthanide cations is obtained by the in situ formation of a polymeric phosphonate-based organic ligand.

In Pr³⁺-doped Y₃Al₅O₁₂, the blue-to-UV upconversion luminescence is significantly more affected by concentration quenching than the UV Stokes luminescence, which is due to cross-relaxation involving the upconversion intermediate states ³P_J and ¹D₂.

Two series of isostructural Ln-MOFs and Ln-doped MOFs were synthesized. Tb-DMF and Tb-DMA are the first to achieve double ratiometric fluorescence sensing of TDGA in real urine. Meanwhile, the doped Ln-MOFs achieve the regulation of emission colors.

A supramolecular fluorescent probe based on unique fluorescence of Eu-complex and precise recognition of pillar[5]arene is developed for two channel simultaneous detection of H₂O₂ and ATP in living cells.

The upconversion of trivalent lanthanide ions (Ln^III) has gained significant attention in recent decades due to its potential applications in energy conversion and biological imaging.

Lanthanide calcium oxyborate LnCa₄O(BO₃)₃ compounds exhibit strong magnetic anisotropy and large rotating magnetocaloric effects, highlighting their potential for low-temperature magnetic cooling applications.

Multi-level luminescent, transparent and non-permanent inks for anti-counterfeiting systems and security were developed.

Lu-MOFs with formic acid as the sole ligand were synthesized by a formamide hydrolysis reaction. The luminescence color and intensity of Lu–Eu-MOFs-bipy can be controlled by the energy competition and transfer between 4,4′-bipyridine and Eu³⁺.

Dopamine and arginine are both important substances in the body and are closely related to human health.

Computational discovery and comprehensive property evaluation of advanced thermal/environmental barrier coatings of high-entropy rare earth disilicates alloys tuned by strong anharmonicity of Eu₂Si₂O₇.

Near-infrared emitting lanthanide ions are efficiently sensitized with excitation in the visible region through the incorporation of amino-substituted bridging ligands within metal–organic framework scaffolds.

Enhanced oxygen electrode performance in solid oxide fuel cells via La-doping of Pr₂NiO_4+δ-based Ruddlesden–Popper perovskites.

A broadband green-emitting BaY₂Sc₂Al₂SiO₁₂:Ce³⁺ garnet phosphor enables warm-white LEDs with high R_a of 93.3 and high LE of 105.3 lm W⁻¹.

We reported the synthesis and crystal structure of a series of rare-earth chalcogenidotetrachloride complexes. Comparative magnetic studies revealed fine but definitive differences due to using different metal and chalcogen elements.

A Ca₃Sc₂Si₃O₁₂:Ce³⁺,Cr³⁺,Li⁺ phosphor-in-glass film with watt-level near-infrared light output upon blue laser-driven lighting shows potential application in night vision and non-destructive analysis and identification.

High-efficiency photocatalytic performance driven by NIR light is realized in β-NaLuF₄:Yb³⁺/Tm³⁺@TiO₂.

Cs₂NaRECl₆ (RE = Tb, Eu) NCs with multicolor emissions under different light excitation have great potential in anticounterfeiting and LEDs.

Sc₂Mo₃O₁₂:Sm³⁺ phosphor was explored for white LED with improved CRI and precise color coordinates for indoor plant growth. The green emission of monoclinic Sc₂Mo₃O₁₂ phase at 80 K diminished on transition to the orthorhombic phase at RT.

A sky-blue OLED based on a Eu(II) complex Eu–tBu shows an EQE_max of 15.7% and a L_max of 52 240 cd m⁻².

Eu-Tb-UiO-66 acts as a highly sensitive luminescent thermometer near room temperature.
