A modified polyol method to prepare silver nanowires (AgNWs) is reported.AgNWs with uniform size and morphology were prepared in the presence of NiCl2
MnCl2 or FeCl3 using high concentration silver nitrate solution (up to 0.4 mol·L-1 in reaction solution).The diameters of the synthetic nanowires ranged from 60 to 100 nm and the lengths were about 30 to 60 μm.The influences of concentration of AgNO3 solution
molar ratio of PVP to AgNO3
and concentration of control agents were investigated.It was found that these conditions could be used to tune the morphology of resultant nanowires.The postulated mechanism relied on removal of adsorbed oxygen from crystal seeds surface by introduced metal cations
