We report here that energy migration during luminescence can be extremely minimized by caging the fluorescent centers in a molecular cluster of [Tb6(μ3-F)8(piv)10(Hpiv)4DMF]·xDMF·yH2O 1. Experimental and theoretical simulations reveal that bonding terbium with fluoride is the key to reducing the non-radiative multi-phonon relaxation processes, which is disparate to the common hydroxy-based lanthanide clusters.
我们在此报告，通过将荧光中心封闭在分子簇[Tb6(μ3-F)8(piv)10(Hpiv)4DMF]·xDMF·yH2O 1中，发光过程中的能量迁移可极大程度地最小化。实验和理论模拟表明，铽与氟化物结合是减少非辐射多声子弛豫过程的关键，这与常见的羟基基镧系簇不同。
