This research work aims at understanding the growth mechanism for silver nanowires by thermal reduction of silver nitrate solution on solid substrate surfaces of titania thin films. Various silver nanostructures were formed under different parameters such as the crystallinity and the phase of the substrates and the thermal processing conditions. Under proper experimental condition, silver nanowires with 30-100 nm in diameter and 1-50 μm in length were formed only on anatase film surfces. Time series growth of various silver nanostructures revealed that the silver nanowires might be formed from the aggregation of silver nanoparticles. The factors influencing the growth kinetics of silver nanowires include thermal reduction temperature, concentration of silver nitrate, thermal reduction time and the amount of silver nitrate solution
