A site-selective fluorescence spectroscopy study of the crystal phases of KY3F10: Leveraging the optical response of Eu3+ ions
Elsevier (2023-04-18)The present work deals with the investigation of the site-selective symmetries in Eu3+-doped KY3F10 with different crystal phases. Employing time-resolved fluorescence line-narrowing (TRFLN), a study of the luminescent ... -
Li2SnO3 branched nano- and microstructures with intense and broadband white-light emission
Springer Verlag (2019)Exploiting the synergy between microstructure, morphology and dimensions by suitable nanomaterial engineering, can effectively upgrade the physical properties and material performances. Li2SnO3 elongated nano- and ... -
One- and Two-Photon Absorption in CdS Nanodots and Wires: The Role of Dimensionality in the One- and Two-Photon Luminescence Excitation Spectrum
American Chemical Society (2014-12)We investigate the spectral dependence of the linear and two-photon absorption of wurtzite CdS nanoparticles (dots and rods) by means of quantitative one- and two-photon photoluminescence excitation spectroscopy and effective ... -
Optical Properties of Hybrid Organic-Inorganic Materials and their Applications
Wiley (2016)Research on hybrid inorganic-organic materials has experienced an explosive growth since the 1980s, with the expansion of soft inorganic chemistry based processes. Indeed, mild synthetic conditions, low processing temperatures ... -
Photoluminescence properties of cerium oxide nanoparticles as a function of lanthanum content
Elsevier (2015)The structural and photoluminescent properties at room temperature of CeO2 and La-doped CeO2 particles were undertaken. The obtained particles were synthesized by a microwave-assisted hydrothermal method (MAH) under different ... -
Polymorphism-Triggered Reversible Thermochromic Fluorescence of a simple 1,8-Naphthyridine
ACS Publications (2013-01-04)The fluorescent behavior in the solid state of a naphthyridine-based donor–acceptor heterocycle is presented. Synthesized as a crystalline blue-emissive solid (Pbca), the compound can easily be transformed in its P21/c ... -
Pyrene-Based Bisazolium Salts: From Luminescence Properties to Janus-Type Bis-N-Heterocyclic Carbenes
WILEY-VCH Verlag GmbH & Co. KGaA (2014-07)A series of pyrene-based bisazolium salts have been obtained starting from 4,5,9,10-tetrabromo-2,7-di-tert-butylpyrene. The synthetic procedure to the pyrene-bisazoliums (PBIs) reveals an unexpected behavior, as a consequence ... -
Solvothermal synthesis of Eu3+-doped holmium aluminum garnet
Elsevier (2015)Eu3+-doped holmium aluminum garnet (Ho3Al5O12, HoAG) has been synthesized by a solvothermal method and annealed at various temperatures. The X-ray diffraction patterns confirmed that single-phase HoAG was obtained already ... -
Tuning the optical and photoluminescence properties of high efficient Eu3+ -doped KY3F10 phosphors by different synthetic approaches
Elsevier (2021)Eu3+-doped KY3F10 materials with a dopant content between 0 and 5 mol% were prepared based on the nominal composition K(Y3-xEux)F10 using different synthetic routes. The reaction conditions have been proven to be critical ... -
Unraveling the superior role of dicarboxylic acids as surface chelators in Eu3+-doped yttrium fluorides: A systematic modulation of the crystal phases and morphologies for highly tuned optical performance
Elsevier (2021-06-16)Eu3+-doped YF3 and KY3F10 phosphors have been prepared hydrothermally in a wide range of pH values without the use of surface chelators and adding oxalic or tartaric acid. We have proved, for the first time, the usefulness ...
