The quantum yield (QY) and lifetime are the important parameters for the photoluminescent materials. The data here report the changes of the QY and lifetime for the quantum dot (QD) nanocomposite after the UV curing of the urethane acrylate prepolymer. The data were collected based on the water soluble CdTe QDs and urethane acrylate prepolymer. Colloidal QDs were in various concentration from 0.5×10(-3) molL(-1) to 10×10(-3) molL(-1), and 1% (wt%) 1173 was the photoinitiator. The QY before the curing was 56.3%, 57.8% and 58.6% for the QDs 510 nm, 540 nm and 620 nm, respectively. The QY after the curing was changed to 8.9%, 9.6% and 13.4% for the QDs 510 nm, 540 nm and 620 nm, respectively. Lifetime data showed that the lifetime was changed from 23.71 ns, 24.55 ns, 23.52 ns to 1.29 ns, 2.74 ns, 2.45 ns for the QDs 510 nm, 540 nm and 620 nm, respectively.
量子产率（QY）和寿命是光致发光材料的重要参数。此处数据报告了聚氨酯丙烯酸酯预聚物紫外线固化后量子点（QD）纳米复合材料的QY和寿命变化。数据基于水溶性CdTe量子点和聚氨酯丙烯酸酯预聚物收集。胶体量子点的浓度范围为0.5×10（-3）molL（-1）至10×10（-3）molL（-1），1%（重量）的1173为光引发剂。固化前，510nm、540nm和620nm量子点的QY分别为56.3%、57.8%和58.6%。固化后，510nm、540nm和620nm量子点的QY分别变为8.9%、9.6%和13.4%。寿命数据表明，510nm、540nm和620nm量子点的寿命分别从23.71ns、24.55ns、23.52ns变为1.29ns、2.74ns、2.45ns。
