Through the envision of inorganic complexation reaction, the assembly of ligand-stabilized gold NCs is possible with metal ions, which supersedes the constituent clusters in terms of tailorable structural properties and hold potential in the advancement of the field. Also, facile development of higher dimension cluster assembly with intriguing optical and physio-chemical properties along with well-defined geometries is achievable. In this context, the effects of transition metal ions and lanthanide metal ions for assembling NCs were investigated for such formation of crystalline nanostructures, which could induce the possibility of amplification in multifunctional properties. The present thesis is divided into five chapters. Details of works incorporated are briefly discussed here.enThesis
