Summary: A series of luminescent lanthanide beta-diketonate solid solutions were synthesized in this study, showing significant increase in emission efficiency of Eu3+ in the presence of non-luminescent chelates, while the ligand phosphorescence was quenched in the solid solutions. Each Eu3+ center may receive excitation energy from approximately 30 ligands, suggesting exciton-like behavior in the solid solutions. Crystallography analysis revealed efficient triplet exciton diffusion through pi-pi stacking of TTA(-) ligands in neighboring units.

Summary: A novel design strategy using dinuclear lanthanide (Ln(III)) complexes was demonstrated for the formation of stacked organic fluorophores and excimers. The rigid aggregation structures of the ligands around Ln(III) resulted in high thermal stability and excimer-type green emission. The change in Ln(III) ion promoted effective shifts of excimer emissions and temperature-sensitive ratiometric emission composed of p-p* and 4f-4f transitions.

Summary: Chelate phosphine oxide ligand (9,9-dimethyl-9H-xanthene-4,5-diyl) bis (diphenylphosphineoxide) (XPO) is used as a neutral ligand to synthesize complex Nd (TTA)(3) (XPO) (TTA = 2-thenoyltrifluoroacetone). The appropriate energy gap between XPO and TTA ligands supports energy transfer from T-1 state of XPO to TTA, leading to improved energy transfer in the Nd complex. Optical gains at 1.06 and 1.31 μm are achieved in Nd (TTA)(3) (XPO)-doped polymer waveguides using low-power LEDs as pump sources instead of semiconductor lasers.

Summary: The key factor limiting optoelectronic performances of organic-inorganic hybrid systems, which is defect, has been overcome through interfacial passivation by electron transporting layers (ETL). By using TmPyPB as ETL, the photoluminescence (PL) and electroluminescence (EL) quantum efficiencies of monophosphine Cu4I4 cube [TPP](4)Cu4I4 are significantly improved, resulting in a huge increase in luminance from nearly unlighted state to highly bright state. The passivation effect of TmPyPB on surface defects of cluster layer is manifested in the prevention of interfacial charge trapping and suppression of exciton nonradiation.
