Synthesis and characterisation of ZnS quantum dots encapsulated zeolitic imidazolate frameworks

Abstract In this work, we report the encapsulation of semiconductor Zinc sulphide quantum dots (ZnSQDs) in Zeolitic Imidazolate Frameworks such as ZIF-8 and ZIF-67. Encapsulated MOF (ZnSQDs@ZIF-8 and ZnSQDs@ZIF-67) composites were prepared by bottle around ship method. The morphology of the encapsulated microstructure were characterised by TEM and SEM. These composites were further characterized for FT-IR and XRD. Thermal stability of ZnSQDs@ZIFs was determined by Thermo gravimetric analysis (TGA).
