White luminescent hybrid soft materials of lanthanide (Eu3+, Sm3+) beta-diketonates and Ag/Ag2S nanoparticles based with thiol-functionalized ionic liquid bridge

Dye-sensitized lanthanide containing nanoparticles for luminescence based applications

“…In 2014, Yan and colleagues proposed a new approach to obtain a white emitting soft material using [Eu( 16 ) 4 ], [Sm( 17 ) 4 ] or [Eu( 128 ) 4 ] complexes linked to Ag-NPs thanks to a thiol-functionalized ionic liquid (SHIL). 281 By changing the number of complexes bound to Ag-NPs, the luminescence colour of the soft hybrid material was adjusted thanks to the band gap differences between the Ln( iii ) complexes and the NPs. Among the different systems, only Ag-SHIL-[Eu( 128 ) 4 ] 3 , Ag-SHIL-[Sm( 17 ) 4 ] 3 and Ag-SHIL-[Eu( 16 ) 4 ] 3 systems displayed white luminescence.…”

Thermal Stability and Luminescent Properties of Tri-cellulose Acetate Composites Containing Dy(SSA)3Phen Complex

“…Considerable attention has been paid to design and synthesize polymer/RE luminescent materials with good luminescent properties and high internal quantum efficiencies [6][7][8]. RE-based emitters which are usually doped or bonded with macromolecules can generate characteristically sharp and narrow emissions, because of the distinctive excitation mechanism of antenna effect and f-f radiative transition [9][10][11][12][13][14]. A considerable number of research reports have focused on four kinds of RE metals, i.e., europium (Eu), terbium (Tb), samarium (Sm), and dysprosium (Dy), especially for the Eu or Tb ions based complexes, because their resonance energy levels are close to the triplet levels of organic ligands, and so the RE ions could emit strong luminescent properties via the efficient energy transfer between ligands and RE ions [15][16][17][18][19].…”

“…Notably, doping luminescent RE organic complexes into polymer matrices is one of the most effective approaches to obtain the polymer luminescent materials via a simple, convenient, and high efficient blending method. However, some doped-polymer/RE composites exhibited poor luminescent properties and poor mechanical properties, mainly owing to the nonuniform dispersion of RE complexes in polymer matrices and the poor chemical affinity between the doped complex and polymer matrix [9,20]. In order to solve these problems, organic ligands of RE complexes play a significant role in boosting the chemical affinity between the added complexes and macromolecules, and especially the organic compounds possessing multifunctional groups which could be potential hydrogen-bonding acceptors or donors are primarily selected as ligands for RE complexes [21][22][23].…”
