Abstract Broadband near‐infrared (NIR) phosphors have recently received considerable attention in spectroscopy technology fields, but designing inexpensive, emission peaks centered above 800 nm, and multimodal broadband NIR luminescence material still remains a great challenge. Here, by selecting stannate compound Mg 2 SnO 4 (MSO) as the host, kind of phosphor MSO:Cr 3+ with multimode properties is reported. The designed exhibits an peaking at nm full‐width half maximum 180 (≈2730 cm −1 )....
K2 TiF6 :Mn4+ is a highly efficient narrow-band emission red phosphor with promising applications in white light-emitting diodes (LEDs) and wide-gamut displays. Nevertheless, the poor moisture-resistant properties of this material hinder commercialization. A convenient reverse cation-exchange strategy introduced for constructing core-shell-structured @K2 phosphor. The outer shell acts as shield preventing moisture air from hydrolyzing internal MnF62- group, while effectively cutting off path...
Lanthanide (Ln3+)-doped photon avalanche (PA) upconversion nanoparticles (UCNPs) have great prospects in many advanced technologies; however, realizing efficient PA luminescence Ln3+-doped UCNPs remains challenging due to the deleterious surface and lattice quenching effect. Herein, we report a unique strategy based on pyrolysis of KHF2 for controlled synthesis aliovalent KMgF3 UCNPs, which can effectively protect Ln3+ from by internal OH- defects thereby boost luminescence. This enables us...
Cr<sup>3+</sup>-free near-infrared persistent luminescence materials from nontoxic Fe<sup>3+</sup>-activated LiGaO<sub>2</sub> phosphors were developed and systematically investigated.

Lanthanide (Ln3+)-doped upconversion nanoparticles (UCNPs) often suffer from weak luminescence, especially when their sizes are ultrasmall (less than 10 nm). Enhancing the luminescence (UCL) efficiency of UCNPs has remained a challenge that must be undertaken if any practical applications to envisaged. Herein, we present Ln3+-doped oxysulfide@fluoride core/shell heterostructure which shows efficient UCL properties under 980 nm excitation and good stability in solution. Through epitaxial...

Abstract Lanthanide (Ln 3+ ) oxysulfide nanocrystals (NCs) have great prospect in many advanced technologies; however, they suffer from a low photoluminescence efficiency due to the volatility of sulfur and deleterious surface quenching effect. Herein, we report novel sandwiched luminescent heterostructure based on Ln ‐doped Gd 2 O S@NaYF 4 core/shell NCs with tunable content sandwich layer. By means Eu as sensitive structural probes, unravel ligand‐mediated structure control 3 : @NaYF S:...

Abstract Lanthanide ion contained metal–organic frameworks (MOFs) have garnered significant attention in the fields of solid‐state lighting and chemical sensing due to their porous structure distinctive optical properties. However, they also present challenges because limited photoluminescence (PL) intensity resulting from parity‐forbidden f–f transitions lanthanide ions. Herein, study reports a new heterometallic MOFs Ln 3 Li 2 L 4 (Li‐Ln‐MOF, = Y, Eu, Tb Dy, deprotonated...
