| Abstract: | Fiber-like gold particles were prepared by irradiation of HAuCl(4) solutions at 253.7 nm in the presence of alkyltrimethylammonium chlorides (C(n)TAC: n=10, 12, 14, and 16). Fiber-like gold particles were obtained above a threshold concentration of C(n)TAC. The length of fiber-like gold particles increases with increasing alkyl chain length of C(n)TAC.
