Lanthanide-doped luminescent perovskites: A review of synthesis, properties, and applications

Methods, progresses, and opportunities of materials informatics

“…Perovskites have attracted much attention due to their easy synthesis, controllable structure, and diverse composition. To date, thousands of perovskites have exhibited various properties in the laboratory, including catalysis, 158,159 thermoelectricity, 160,161 ferroelectricity, 162,163 solar cells, [164][165][166] lasers and photodetection, 167,168 and so on.…”

Multi-emission processes of hierarchically structured NaGdF4:Tm:Yb:Tb core@shell nanoparticles

“…1a. 9 The hexagonal (b) NaREF 4 phase is more adequate towards boosting the Ln III luminescence since the Ln III local sites displaying lower symmetry (no inversion center) than the cubic (a) phase favor the intermixing of the 4f n configuration with upper-energy electronic configurations states displaying opposite parity, leading to more relaxed intraconfigurational transitions occurring by the forced electrical dipole mechanism. 10 One concern regarding the design of Ln III -doped NaREF 4 nanoparticles is the surface chemistry because the doping ions on the surface are exposed to several non-radiative pathways, namely surface defects, lattice strains, energy migration, as well as ligands and solvents displaying high phonon energy (4 1000 cm À1 ).…”

PMMA or PVDF films blended with β-diketonate tetrakis EuIII or TbIII complexes used as downshifting coatings of near-UV LEDs

“…However, it is worth highlighting that there is a current call to develop new phosphors for such application, featuring high emission quantum yields. 17 The state-of-the-art of phosphors for WLEDs are based on Eu II , Mn II , Mn IV or Ce III as optical centers, 16 obtained under hard synthesis conditions (expensive processes, controlled atmosphere, high annealing temperatures) and presenting wide emission bands extending to the near infrared region. These are disadvantages that can be surpassed using luminescent complexes containing Ln III , such as the red-emitting Eu III or the green-emitting Tb III .…”
