Designing photochromic materials with large luminescence modulation and strong photochromic efficiency for dual-mode rewritable optical storage Ghent University
Inorganic materials combining photochromism and luminescence modulation characteristics have great potential in dual-mode rewritable optical storage due to their unique optical features and excellent thermal stability. However, the failure of achieving a large luminescence modulation and a strong photochromic efficiency in photostimulated inorganic photochromic materials limits their applications. Herein, a new strategy for realizing an overlap ...
Improved quantum yield and excellent luminescence stability of europium-incorporated polymeric hydrogen-bonded heptazine frameworks due to an efficient hydrogen-bonding effect Ghent University
Two of the most persistent challenges for the high-end application of luminescent lanthanide (Ln) compounds are a low quantum yield and luminescence quenching caused by a liquid medium. In this work, a type of polymeric hydrogen-bonded heptazine framework is developed incorporating trivalent europium ions (P-HHF-Eu) via a low-cost and facile low-temperature thermal condensation reaction. Structural characterization clearly reveals that the ...
Identifying near-Infrared persistent luminescence in Cr3+-doped magnesium gallogermanates featuring afterglow emission at extremely low temperature Ghent University
Room-temperature persistent phosphors emitting in a wide spectral range are extensively explored owing to their commercial interest in applications such as night-vision signs and medical imaging. However, phosphors featuring long-lasting near-infrared emission at extremely low temperature are barely reported so far. Herein, a design of trivalent chromium-activated magnesium gallogermanates (Mg1+xGa2-2xGexO4:Cr3+) is demonstrated that exhibit ...
Enhanced near-infrared persistent luminescence in MgGa2O4:Cr3+ through codoping Ghent University
Near-infrared emitting persistent luminescent materials have potential applications in night-vision surveillance and medical imaging. Rational designing of the phosphor composition is of great importance for achieving sufficiently strong and long-lasting persistent luminescence. Herein, a series of MgGa2O4:Cr3+ phosphors with variable concentrations of Cr3+ were prepared via solid state reaction. MgGa2O4:Cr3+ exhibits strong emission in the ...
