Abstract:In this work, cadmium oxide (CdO) nanostructures were fabricated in good yields by calcining three different cadmium-based coordination polymer (CP) precursors, with a change in the alkyl group (methyl, ethyl, and tert-butyl) on the tridentate capping ligand, at 600 °C. The precursor-independent spherical morphology was observed in all the cases. On the other hand, a temperature-dependent hierarchical evolution of morphology from spherical (at 600 °C) to octahedron (at 700 °C) to icosahedron (at 800 °C) was o… Show more
