Abstract
- The new class of Tricarboxylate-Bismuth (TB)-based Metal Organic Frameworks (MOFs) was attempted, using the impressive capability of alkaline earth metal Bismuth (Bi), to realize more massive complex structures for real-world applications including supercapacitors, energy storage devices, biomedical imaging, drug delivery, fluorescence sensing and far-UVC applications. The grown structure and band gap of the TB-based MOFs samples were characterized by X-ray diffraction analysis (XRD), scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDS), Raman spectroscopy, and Ultraviolet-Visible Absorption Spectroscopy (UV-Vis spectra), respectively. The SEM observation identifies the TB-based MOFs nanosheet layered with orthorhombic structure, which shows strong agglomeration with a grain size of 668 nm. The EDS analysis indicates the presence of Bi-peaks as well as carbon peaks (organic linkers) in the grown samples. Furthermore, the peak of TB-based MOFs structure during the Raman spectroscopy was also confirmed. The optical band gap of the newly synthesized TB-based MOFs was estimated and the optical band gap ( E g) approximately ∼ 5. 4 5 eV was confirmed. These findings open the possibility of Bi-based MOFs for the applications in far-UVC emission range. [ABSTRACT FROM AUTHOR]
