Example Embodiment
[0018] Example 1:
[0019] Prepare 10ml 1mM HAuCl in a round bottom flask 4 Aqueous solution, magnetically stirred, and then drop 0.5ml 200mM Na in the reactor 2 EDTA aqueous solution, HAuCl 4 With Na 2 The molar ratio of EDTA is 1:10, the reaction temperature is set to 25° C., the reaction is stopped for 3 hours, and the obtained precipitate is centrifuged and washed to obtain gold microcrystals with a multi-branched surface with surface enhanced Raman activity. Perform scanning electron microscopy characterization, see Figure 1.
Example Embodiment
[0020] Example 2:
[0021] The reaction temperature was set to 50° C., and other test conditions were the same as in Example 1, and gold microcrystals with multi-branched surfaces with surface enhanced Raman activity were obtained. The resulting product was characterized by scanning electron microscopy, see Figure 2.
Example Embodiment
[0022] Example 3:
[0023] The reaction temperature was set to 100° C., and other test conditions were the same as in Example 1, and gold microcrystals with multi-branched surfaces with surface enhanced Raman activity were obtained. The obtained product was characterized by scanning electron microscopy, see Figure 3.
