This work reports the compounds [Zn2(bdc)2dabco] (ZBDh) and [Zn2(bdc)2dabco] (ZBDt) and their composite Eu2O3@[Zn2(bdc)2dabco] (ZBDh) synthesized by pulsed laser ablation in flowing liquid. At an appropriate reactant concentration, phase ZDBh transforms into phase ZDBt by an increase of the irradiation time from 4 to 40 min. The results show that the Eu2O3 nanoparticles with an average size of 3.17 nm are uniformly distributed throughout the crystal and the BET specific surface area of the composite Eu2O3@[Zn2(bdc)2dabco] (ZBDh) is 1621 m2 g−1, which is larger than that of compound [Zn2(bdc)2dabco] (ZBDh). Moreover, the composite Eu2O3@[Zn2(bdc)2dabco] (ZBDh) can emit very intense characteristic fluorescence at 613 nm of the Eu3+ ion under ultraviolet radiation and can be used for detecting methanol molecules in fluorescence sensing because its fluorescence intensity at 613 nm is sensitive to the content of methanol in solvent.

金属-有机骨架及其复合Eu2O3 @ [Zn2（bdc）2dabco]（ZBDh）的制备和表征
这项工作报告化合物[Zn 2（bdc ）2 dabco]（ZBDh）和[Zn 2（bdc ）2 dabco]（ZBDt）及其复合Eu 2 O 3 @ [Zn 2（bdc ）2 dabco]（ZBDh）在流动的液体中通过脉冲激光烧蚀合成。在适当的反应物浓度下，通过将照射时间从4分钟增加到40分钟，相ZDBh转变为相ZDBt。结果表明，平均粒径为3.17 nm的Eu 2 O 3纳米颗粒均匀地分布在整个晶体中，并且复合Eu 2 O 3 @ [Zn 2（bdc ）2 dabco]（ZBDh）为1621 m 2 g -1，比化合物[Zn 2（bdc ）2 dabco]（ZBDh）大。此外，复合Eu 2 O 3 @ [Zn 2（bdc ）2 dabco]（ZBDh）在紫外线下可在Eu 3+离子的613 nm处发出很强的特征荧光，可用于检测荧光传感中的甲醇分子因为它在613 nm处的荧光强度对溶剂中甲醇的含量敏感。
