Abstract
Novel cobalt(II) metal-organic framework was grown by the reaction of a methanol solution of 8-hydroxyquinoline and benzoic acid with aqueous solution of cobalt(II) chloride hexahydrate using slow solvent evaporation. The X-ray luminescence of the synthesized compound showed vibronic peaks: one with λmax at 489 nm and shoulders at 424 and 531 nm, respectively, which compare favorably with best organic scintillators such as anthracene –447 nm and stilbene –410 nm currently in application. The elemental analysis of the metal complex suggests a metal to ligands ratio of 1:1:1. Conductance measurement shows a nonelectrolytic nature of the synthesized compound. The SEM studies give the surface morphology of the complex. The observed emission bands with different dynamics in response to temperature change suggest that the Co-MOF exhibits scintillation properties. Electronic spectrum and magnetic moment studies were used to determine the geometry of the Co-MOF molecule. Thermal analysis data reported displayed the extent of stability of the Co-MOF compound. PXRD data revealed the nanocrystalline nature of the complex. Energy resolution peak observed at 2535 KeV, suggest the synthesized compound can be used as a scintillator.
