中文摘要: |
通过一锅水热法制备了在MOF-808纳米笼中包含吖啶黄染料的AF@MOF-808,并通过X射线粉末衍射仪(XRD)、扫描电子显微镜(SEM)和热重分析(TGA)对其结晶、形貌和稳定性进行了表征。AF@MOF-808能发出明亮的绿光,量子产率高达38.27%,并能从12种金属离子或阴离子的水溶液中选择性地检测出Fe3+离子和Cr2O72-阴离子。 |
英文摘要: |
AF@MOF-808 incorporating the acriflavine (AF) dye into the nanocages of MOF-808 was constructed by one-pot hydrothermal method, whose crystallization, morphology and stability were characterized by the X-ray powder diffractometer (XRD), scanning electron microscope (SEM) and thermogravimetric analysis (TGA). AF@MOF-808 exhibit the bright green light emission with the high quantum yield of 38.27%, which also showed the selectively detection of Fe3+ ion and Cr2O72- anion from 12 kinds of metal ions or anions in the aqueous solution. |
