| description | The invention discloses a method for synthesizing gold nanospheres, which comprises the following steps of: firstly preparing a CTAB (Cetyltrimethyl Ammonium Bromide) encapsulated gold cluster, then adding CTAC (Cetyltrimethyl Ammonium Chloride), AA (Acrylic Acid) and sodium oleate to synthesize the gold nanospheres with smaller diameters, adding HAuCl4 and a 1, 2, 3 trihydroxy benzene solution on the basis of the gold nanospheres with smaller diameters, heating and stirring to synthesize gold nanosphere polyhedrons. And finally, carrying out light oxidation by using a HAuCl4 solution to generate the gold nanospheres with the diameter of 20-200nm. The success of this synthesis depends on the use of single crystal gold balls of different diameters as seeds for continuous growth, the diameters can be precisely controlled by changing the size and/or number of the seeds. The synthesized gold nanospheres show excellent uniformity in the aspects of size and shape, the preparation time is very short, and the gold na |
