摘要
本文利用π-π堆积的方式在氧化石墨烯(GO)表面生长了Eu髥配合物纳米晶。傅立叶变换红外光谱(FTIR),透射电子显微镜(TEM),X-射线衍射(XRD)的表征证明,Eu髥配合物纳米晶成功地生长在氧化石墨烯表面。荧光光谱分析证明,复合材料具有一定的荧光性能,其中Eu3+的猝灭浓度为18wt%。热重分析显示,复合材料的热稳定性也比纯配合物有了明显的提高。
In this study, Eu(Ⅲ) complex nanocrystals had grown on graphene oxide (GO) by π-π stacking. Fourier transform infrared spectroscopy (FTIR), transmission electron morphology (TEM) and X-ray diffraction (XRD) were used to demonstrate the successful growth of Eu(Ⅲ) complex nanocrystals on GO surface. Investigations using fluorescence spectroscopy proved the fluorescence property of the composite and the fluorescence quenching concentration of Eu3+ was 18wt%. Thermogravimetric analysis(TGA) showed that the thermal stability of the composite had been remarkably improved comparing with pure complex.
