Web3 hours ago · Thales operates the largest quantum physics research facilities in Europe, in partnership with the CNRS, and some 100 engineers and researchers are currently engaged in the development of the ... WebAbstract. Here, we report two europium(III) complexes (Eu1 and Eu2) with high photoluminescence quantum yield, based on tridentate isoquinoline derivatives (HL1 and HL2).The single crystal structures of Eu1 and Eu2 show that three ligands coordinate with an Eu(III) ion through diphenylphosphoryl oxygen, pyridyl nitrogen and carboxyl oxygen … instance of response dynamic

WebHerein we describe luminescent europium nanoparticles that have an excitation peak around 406 nm with high quantum yield (∼66%) and fine monodispersity in aqueous solutions. WebWe have prepared complexes of formula [Eu(β-diketonate)3(DPEPO)] and shown quantitative excited-state energy transfer from the ligands combined with efficient Ln luminescence leading to exceptionally-high total photoluminescence quantum yield of up to 80% in solution and in PMMA. Webquantum yield of the Eu3+ (or Tb3+) luminescence for com-pounds was evaluated by comparing integrated luminescence intensities with that of 1 (exhibiting sharp 5D0f7FJ (J ) 0-4) lines with a quantum yield (…) ) 1.0 at 4.2 K)1g under the same arrangement of the pellet.
