Embodiment 1
[0061] (1) In the air, put 1.25*10 -2 mmol tetrachloroauric acid and 5*10 -2 Add mmol copper chloride to 6mL oleylamine, stir and mix well.
[0062] (2) In the air, place the solution in step (1) in an oil bath at 180° C. and stir, react for 2 minutes and 30 seconds, centrifuge, discard the supernatant, and wash the bottom precipitate (n-hexane: ethanol=1 : 1, three times) to obtain gold nanowires with a variety of close-packed structures mixed and arranged randomly. Its transmission electron microscope pictures are shown in figure 1 middle.
Embodiment 2
[0064] (1) Set 1.25*10 -2 mmol tetrachloroauric acid and 5*10 -2 Add mmol copper chloride to 6mL oleylamine, stir and mix well.
[0065] (2) Stir the solution in step (1) in an oil bath at 170°C, centrifuge after reacting for 3 minutes, discard the supernatant, and wash the bottom precipitate to obtain gold nanowires with a variety of close-packed structures mixed in random arrangements . Its transmission electron microscope pictures are shown in figure 2 middle.
