We demonstrate the first example of exfoliated layered europium hydroxide (LEuH) composites with a fluorescent molecule that exhibit blue luminescence. Co-quenching in the solid state, blue emission (440 nm) in formamide, and green emission (514 nm) in water-formamide were found, for which delamination and swollen states account for the versatile luminescence behaviors.
我们展示了首例具有荧光分子的层状氢氧化铕（LEuH）剥离复合材料，其呈现蓝色发光。发现了固态中的共猝灭、在甲酰胺中的蓝色发射（440 nm）以及在水 - 甲酰胺中的绿色发射（514 nm），分层和溶胀状态解释了这些多样的发光行为。
