    Abstract

    A novel laser-liquid-solid interaction (LLSI) technique has been developed that is highly flexible and allows engineering nanomaterials in form of particles, rods, and tubes from liquid precursors. Synthesis reaction takes place in a molecular level and reaction rate is controlled by laser energy input, precursor solution chemistry, and other processing parameters including interaction time, and thermal conductivity of solid that is spinning in the solution. By the proper selection of liquid precursor, mono-dispersed silver nanoparticles were produced with average particle size 7-10nm. Alloy composed Ag and Ni were produced in the form of nanoparticles and nanotubes with an average diameter of 40nm. HRTEM of nanorod exhibited that Ag acted as seed for the synthesis of immiscible of Ag-Ni alloy. Laser writing of silver exhibited 50% lower electrical resistivity and eliminated many intermediate steps involved as compared to conventional silver patterning process.
