Abstract
The characterization of the triplet state of decatungstate (DT*) and its NIR phosphorescence with lifetimes ∼100 ns in acetonitrile allow the easy determination of rate constants that are key to understanding its role in catalysis. The absence of oxygen quenching can now be understood as the excitation energy of DT* is lower than the energy of singlet oxygen.
摘要
十钨酸盐三重态（DT*）的表征及其在乙腈中具有约100纳秒寿命的近红外磷光，使得能够轻松测定速率常数，而这些速率常数是理解其在催化作用中所起作用的关键。由于DT*的激发能量低于单线态氧的能量，现在可以理解为什么不存在氧猝灭现象了。
