采用3种配体合成一种壳层很薄且无法将纳米晶完全包覆的钙钛矿纳米晶核壳结构,并通过X射线衍射(XRD)和透射电子显微镜(TEM)表征证明此不完全包覆的纳米晶核壳结构成功制备。相比于原始钙钛矿纳米晶,该钙钛矿量子点核壳结构具有较好的稳定性,可与相关金属离子接触发生电子转移,使量子点的荧光发生猝灭,达到检测重金属离子的目的。所制备的钙钛矿纳米晶核壳结构可灵敏地检测铜离子和汞离子,理论检出限分别为0.60 nmol/L和0.64 nmol/L。该研究对开发新型量子点荧光检测剂具有重要意义。
In this study,three ligands were used to synthesize a kind of perovskite nanocrystals core-shell structure with a very thin shell layer that nanocrystals cannot be completely coated with this core-shell. Compared with the original perovskite nanocrystals,the core-shell structure of the perovskite quantum dots has better stability,and also has pores that can contact with related metal ions,so that the fluorescence of the quantum dots can be quenched,so as to achieve the purpose of detecting heavy metal ions. The perovskite nanocrystalline core-shell structure prepared in this study can sensitively detect copper and mercury ions,and the theoretical detection limit of Cu,2+, can reach 0.60 nmol/L,while the theoretical detection limit of Hg,2+, can reach 0.64 nmol/L. This study is of great significance for the development of novel fluorescence detection agents for quantum dots.
