Metal Organic FrameWork Encapsulated Luminous Quantum Dots Functional Composite for OptoelectronicApplications

Abstract

Metal-organic frameworks (MOFs) offer substantial structural benefits and outstanding application in numerous industries, due to their huge specific surface area, high porosity, open pore structure, and easily changeable and functionalized porous surface. However, MOFs by themselves have several limitations, including low stability, set pore size, and restricted electrical conductivity. The innovative incorporation of QDs into MOF structures can get beyond these restrictions. While the host (MOFs) framework offers optimal connections to the guest (QDs) for improving stability, extended carrier lifetime, improved, greater photoluminescence quantum yield, and synergic features, the resulting host-guest structure exhibits a wide variety of synergetic qualities. In this research project novel Zif-67@ZnSe-QDs composites are synthesized by facile wet chemical method. The photoluminescence spectroscopy technique was employed to explore the optoelectronic applications focusing on luminescence/sensing properties of the synthesized composites. The UV-visible spectroscopy was done to estimate the band gap of the composites. The crystallographic structure of the composites was studied using XRD. FTIR and Raman spectroscopy was used to examine the vibrational modes and functional groups of the materials. SEM analysis was used to determine the morphology of the samples.
