Fabrication and analysis of barium-based metal organic framework characteristic properties

Abstract

Metal Organic framework (MOFs) a diverse class of complex organic metal assemblages has been attracting a great interest due to its easy tunability and modified characteristics during the past few years. These nanoscale-to-microscale-sized structures have been employed in different applicative fields due to their striking functional chemistry. Barium MOF synthesis is based on barium metal ions tri-linked organically to form a cubic structure and features photolumincity. Ba-MOF was synthesized by hydrothermal method and structural and optical analysis was performed using X-ray Diffraction (XRD), Scanning Electron Microscopy (SEM), Energy Dispersive Spectroscopy (EDS), Raman Spectroscopy and Zeta Potential. The presence of cubic structure and organic carbon and oxygen linkages was indicated by XRD peaks. EDS directs the presence of barium as well as carbon and oxygen (organic linkers). Raman analysis paid for witnessing the evidence of the synthesis of MOF structure by validating the peak location. The photoluminescence spectrum was applied to measure the bandwidth to study the photoluminescence characteristics. The PL spectrum presented a wide bandwidth of 107.4 nm indicating Ba-MOF to be an efficient photoluminescent nanocomposite for photoluminescence-based applications. Zeta potential value of [Formula: see text] mV characterized anionic behavior and high stability of fabricated Ba-MOF.
