Abstract:
1. A method of forming nano-rods, the method comprising: forming seed particles comprising a metal oxide, in a first solution; removing the seed particles from the first solution; and forming nano-rods in a second solution comprising the seed particles dispersed therein, a metal precursor of a metal of the metal oxide, and an organic solvent, such that each of the seed particles grows in two opposing directions, to form the nano-rods extending in a direction substantially parallel to the two opposing directions and being larger than the seed particles, wherein the nano rods are formed at a temperature between about 200° C. and about 340° C., and wherein the nano rods are formed by reacting about 0.05 mmol to about 0.35 mmol of the seed particles, about 0.1 mmol to about 1.5 mmol of the metal precursor, and about 0.5 mmol to about 3.5 mmol of a surfactant with about 1 g to about 10 g of the organic solvent.
