Abstract

We present a novel molecular upconversion materials based on a discrete lanthanide–polyoxometalate (Ln–POM) complex. A lacunary-type silicotungstate, [γ-SiW₁₀O₃₆]⁸⁻ (SiW), forms a dinuclear Yb-POM complex, [Yb₂(μ₂-OH)₂(γ-SiW₁₀O₃₆)₂]¹²⁻ (Yb-SiW), which exhibits upconversion luminescence via cooperative luminescence mechanism in the visible region upon near-infrared excitation of its two Yb ions in CD₃CN.

分立无机分子上转换：双核镱-多金属酸氧配合物显示协同上转换发光

我们提出了一种基于离散镧系-多金属氧酸盐（Ln-POM）配合物的新型分子上转换材料。孔型钨酸硅[γ-SiW10O36]8−(SiW)在CD3CN中形成双核Yb- pom配合物[Yb2(μ2-OH)2(γ-SiW10O36)2]12−(Yb-SiW)，其两个Yb离子在近红外激发下在可见光区通过协同发光机制产生上转换发光。
