Summary: Upconversion is a promising anti-Stokes-like optical process with potential applications in diverse fields. However, current known mechanisms for upconversion are mainly based on direct energy transfer between metal ions, which limits the design and tunability of the structures and properties. By synthesizing lanthanide-organic complexes with assembly induced excited-multimer states, we demonstrate a new strategy for designing upconversion materials that is crucial for exploiting the photofunctions of multicomponent lanthanide-organic complexes.

Summary: Despite extensive efforts, little progress has been made in combating thermal quenching in luminescent materials. This study demonstrates that controlled annealing can form Frenkel defect in Sc-2(WO4)(3):Ln (Ln=Yb, Er, Eu, Tb, Sm), which acts as an energy reservoir and transfers the stored excitation energy to Ln(3+) upon heating. This discovery opens up new avenues for reliable generation of high-temperature luminescence.

Summary: Lanthanide metal complexes with light-harvesting organic chromophoric moieties have been extensively studied in various technological sectors due to their outstanding performance. Organic compounds for sensitizing luminescence in lanthanides are being explored to produce new lanthanide compounds. Lanthanide complexes are excellent materials for solid state lighting and electroluminescent displays due to their emission characteristics, color range, and quantum efficiency. This review focuses on the synthesis of lanthanide beta-diketonate complexes with 2,2'-bipyridine and 1,10-phenanthroline, as well as their derivatives, and characterization techniques including elemental analysis, spectroscopy, mass spectrometry, and X-ray diffraction.

Summary: The ligand H3L has been used to study energy transfer in dinuclear lanthanide analogues, showing that ET between Eu-III and Yb-III does not occur significantly, and that Yb-III emission originates from sensitization by the ligand. Energy migration seems to occur between the two Nd-III centers, with Yb-III luminescence being partially sensitized by ET from Nd.

Summary: This paper investigates the photosensitization mechanism of Yb3+ and Sm3+ ions in CsPbCl3 perovskite nanocrystals, revealing that the first step of photosensitization is electron transfer, followed by the formation of the emissive species Ln(3+)*. This mechanistic understanding provides a framework for selecting the right combination of host matrix and Ln(3+) species for efficient photosensitization.

Summary: Trivalent lanthanide ions (Ln(3+)) have unique atomic-like emission spectra and long luminescence lifetimes, making them important in the field of optoelectronic materials. Metal-organic frameworks (MOFs) and coordination polymers are suitable luminescent materials due to their structural diversity and ease of functionalization. This article presents a series of mixed-metal Ln(3+)/Eu3+ and mixed-ligand MOFs, which show emissions across the visible region and have potential applications in color tuning and white-light emission. The study investigates the thermal stability and photo-physical properties of the synthesized materials, discussing excimer and monomer emission as well as energy migration and Eu3+ sensitization pathways. The results demonstrate high emission quantum yields for Eu3+-doped materials and the ability to achieve yellow and white-light emission through careful doping level adjustments.

Summary: The urgent need for efficient and high-purity red phosphors in LED development was addressed in this study. The whitlockite compound Ca19Mn2(PO4)(14) with its compact and compositional-tunable structure was chosen as the phosphor host for Eu2+ sensitization. Various analyses were conducted to investigate the properties of Ca19Mn2(PO4)(14): Eu2+, including Rietveld refinement, steady-state spectra, decay lifetime analysis, and temperature-dependent emission spectra. The results showed that Ca19Mn2(PO4)(14): Eu2+ exhibited strong Mn2+ sensitized emission under 360 nm excitation, with excellent emission engineering achieved through Sr2+ co-doping. The phosphor also demonstrated promising thermal stability. Overall, this study highlights the great potential of Ca19Mn2(PO4)(14): Eu2+ phosphor as an efficient red phosphor for phosphor-converted white LEDs.

Summary: In this study, Eu-doped YVO4 single crystals with different concentrations were fabricated to evaluate their photoluminescence and scintillation properties. The results showed that the samples doped with Eu exhibited emission peaks due to 4f-4f transitions in PL and scintillation spectra. Based on the pulse height spectra, the light yield of the Eu-doped samples increased with increasing Eu concentration, while the afterglow level decreased.

Summary: This study successfully prepared phosphor samples based on Ca3-xLuxSc2-xMgxSi3O12:Ce3+ and investigated their luminescence properties. With the increase in Lu-Mg concentration, the peak of the sample redshifted, but the thermal stability gradually decreased. The LD devices made from CLSMS:Ce3+ fluorescent materials showed a decrease in cyan-green light and an increase in red light as the Lu-Mg concentration increased.
