Europium Coordination Compound with Highly Improved Luminescent Quantum Yield

         

摘要

The luminescent properties of two Eu3+ compounds based on quinoline-2-car-boxylic acid (Hqc),[Na2Eu2(qc)6(CH3COO)2(H2O)4]·2DMF (1) and [Eu2(qc)6(H2O)6]3H2O (2),as well as their syntheses and structures are reported.Both compounds are formed by slow evaporation at room temperature and exhibit zero dimensional dinuclear structures.It is worth mentioning that a 4.5-fold enhancement in luminescent quantum yield is achieved by reducing the nonradiative deactivation,through which the quantum yield increases remarkably to 67.62% for 1 compared with 12.18% for 2.
