Silver nanoparticles were synthesized using block copolymer (Pluronic® P123) spherical micelles as a template. In aqueous Ag+ ions may be electrostatically complexed with the anionic surfactant or ionic liquids. The silver ions were reduced in situ by introducing sodium borohydride as a reducing agent. We found that the size of the silver nanoparticles was exclusively depends on the size of block copolymer micelles. Addition of ionic liquid (IL) (1-decyl-3-methyl imidazolium dodecyl sulphate (C10MimDs)) induced sphere – ribbon transition of Silver nanoparticles. The size of the nano ribbon can be tuned by controlling concentration of ionic liquid as well as reducing agents. The silver nanoparticles were observed to be extremely stable in solution suggesting that the modified IL molecules stabilized them. The nanoparticles were characterized by UV-Vis absorbance, dynamic light scattering (DLS) as well as Transmission electron microscope (TEM).
