In recent decades, rare earths have become vital to a wealth of advanced materials and technologies including catalysts, alloys, magnets, optics lasers, rechargeable hydride batteries, electronics, economical lighting, wind- solar-energy conversion, bio-analyses imaging. this perspective article we give broad overview earth resources uses first then selected applications in dedicated fields such as telecommunications, photovoltaics (solar-energy conversion), lighting (fluorescent lamps...
Efficient lanthanide (Ln) luminescent probes require good ligand-to-metal energy transfer and high aqueous stability. A family of ligands based on 2-hydroxyisophthalamide chelating units is reported. These form highly stable, eight-coordinate Ln complexes. Several these (Ln = Sm, Eu, Tb, Dy) emit in the visible region with ligand-to-lanthanide transfer. The absolute quantum yields two Tb complexes studies (Φ 0.59, 0.61) absorbance make brightest for time-resolved detection; emission spectrum...
Because of their remarkable and unmatched optical magnetic properties, the lanthanides are under limelight when it comes to high technology. These elements used in strategic applications such as glasses lasers, telecommunications, lighting displays, materials, hard-disk drives, security inks counterfeiting tags, catalysis, biosciences, medicine, name but a few. Long considered minor actors transition metal chemistry, they have now gained respect from coordination chemists who insert them...
Abstract All-inorganic CsPbX 3 (X = Cl, Br, and I) perovskite quantum dots (PeQDs) have shown great promise in optoelectronics photovoltaics owing to their outstanding linear optical properties; however, nonlinear upconversion is limited by the small cross-section of multiphoton absorption, necessitating high power density excitation. Herein, we report a convenient versatile strategy fine tuning luminescence PeQDs through sensitization lanthanide-doped nanoparticles. Full-color emission with...
Coordination-directed self-assembly has become a well-established technique for the construction of functional supramolecular structures. In contrast to most often exploited transition metals, trivalent lanthanides Ln(III) have been less utilized in design polynuclear self-assembled structures despite wealth stimulating applications these elements. particular, stereochemical control assembly lanthanide chiral cage compounds is not easy achieve view usually large lability ions. We report here...
This essay draws attention to lanthanide luminescence by putting into perspective the sensitization process of f–f emission, design highly luminescent lanthanide‐based compounds, and upconversion nanoparticles. A brief overview recent advances in some applications, namely lighting, security inks tags, as well biological is presented.
The efficiency with which the surroundings of trivalent lanthanide ions sensitize their luminescence (ηsens) is a key parameter in design highly emitting molecular edifices and materials. Evaluation ηsens requires measurement overall intrinsic quantum yields obtained upon ligand metal excitation, respectively. We describe modified integration sphere enabling absolute determination these quantities on small amounts solid samples or solutions (60 μL). tested for linear response emitted versus...
A [Cr(α,α'-diimine)3]3+ chromophore is used as a donor for sensitizing NdIII and YbIII near-infrared (NIR) emitters in the heterobimetallic helicates [LnCrIIIL3]6+. The intramolecular CrIII → LnIII energy transfer process controls population of lanthanide-centered emitting levels, thus leading to unprecedented extension NIR luminescence decay times millisecond range Nd Yb ions incorporated coordination complexes.
