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.

氟化fluor簇：用于光致发光的能量笼。

我们在这里报告的是发光期间能量迁移可以通过在[Tb的分子簇进行封闭而荧光中心的程度非常小₆（μ ₃ -F）₈（PIV）₁₀（HPIV）₄ DMF]· X DMF· ÿ ħ ₂ ö 1。实验和理论模拟表明，with与氟化物的键合是减少非辐射多声子弛豫过程的关键，这与常见的基于羟基的镧系元素簇不同。
