芘磷光掺杂氧传感材料的制备及性能研究

Preparation and characterization of pyrene phosphorescence doping oxygen sensing materials

氧含量是气体产品质量的重要考察指标,基于磷光猝灭的氧含量检测方法具有消耗样品量少和对氧气传感灵敏的优势。本文以芘为磷光材料,利用金属有机框架材料(MOF)做为主体,采用水热法将芘掺杂入化学稳定性好、孔径较小的Zr基MOF材料UiO-66中,合成Pyrene@UiO-66氧传感材料,并将材料制成薄膜进行磷光性能测试。结果表明,芘的掺杂未改变UiO-66材料的结构和稳定性,且Pyrene@UiO-66具有显著的磷光发光,在测试气体中氧含量具有较好的线性。

Oxygen content is an important index to evaluate the quality of gas products.The method of oxygen detection based on phosphorescence quenching has the advantages of less sample consumption and sensitive oxygen sensing.In this paper,pyrene was used as phosphorescent material and metal organic framework(MOF)as the host.Pyrene@UiO-66 materials were prepared by hydrothermal method,using pyrene doping of Zirconium MOF UiO-66 which with good chemical stability and small pore size.The products were made into thin films for phosphorescence test.The results show that the structure and stability of UiO-66 are not changed by the doping of pyrene.The phosphorescence of Pyrene@UiO-66 exhibits significant luminescence.The determination of oxygen content in gas has a good linear.
