Abstract A tetrahedral {HPO3} and {WO4} group simultaneously directing tri-Tb(III)-containing antimonotungstate (AT) K3Na21H[Tb3(Ac)3(HPO3)(WO4)][B-α-SbW9O33]3·36H2O (1) has been triumphantly isolated by the aqueous reaction of Na9[B-α-SbW9O33]·19·.5H2O, Na2WO4·2H2O, H3PO3 and Tb(NO3)3·6H2O. Notably, tetrahedral {HPO3} and {WO4} groups may play the template-directing function in the formation of polyoxoanion of 1. Under the excitation at 380 nm, the emission spectrum and the decay lifetime curve of 1 have been measured. Upon the O → W LMCT excitation at 260 nm, energy transfer from AT fragments to Tb3+ ions has occurred because Tb3+ ions can absorb energy from the O → W LMCT emission of AT fragments. By switching the excitation wavelength from 250 to 390 nm, it’s available to tune the emission color of 1 from blue to green.

四面体{HPO3}和{WO4}基团同时导向含三Tb(III)的抗钨酸及其光致发光特性

摘要四面体{HPO3}和{WO4}基团同时导向含三Tb(III)的抗钨酸(AT) K3Na21H[Tb3(Ac)3(HPO3)(WO4)][B-α-SbW9O33]3·36H2O ( 1) 已通过 Na9[B-α-SbW9O33]·19·.5H2O、Na2WO4·2H2O、H3PO3 和 Tb(NO3)3·6H2O 的水溶液反应成功分离。值得注意的是，四面体{HPO3}和{WO4}基团可能在1的多氧阴离子形成中起模板导向作用。在380nm激发下，测量了1的发射光谱和衰减寿命曲线。在 260 nm 处 O → W LMCT 激发时，发生了从 AT 碎片到 Tb3+ 离子的能量转移，因为 Tb3+ 离子可以从 AT 碎片的 O → W LMCT 发射中吸收能量。通过将激发波长从 250 nm 切换到 390 nm，可以将 1 的发射颜色从蓝色调到绿色。
