[0031] Example 1:
[0032] (1) Preparation of silver nanoflower substrate: the silver nanoflower was prepared by the polyvinylpyrrolidone reduction method, 0.2mL silver nitrate with a concentration of 1.0M and 2.0mL with a mass concentration of 1.0% polyvinylpyrrolidone were added to a 10mL beaker, Magnetically stirred at room temperature for 10 minutes, quickly add 2.0 mL of ascorbic acid solution with a concentration of 0.1M to the above solution. After magnetically stirred at room temperature for 15 minutes, the reaction was terminated and the solution was gray; the silver sol was washed several times with ethanol and ultrapure water. Wash away unreacted reagents, dry and store at room temperature to obtain silver nanoflower substrate; figure 1 In order to obtain the SEM characterization image of the silver nanoflower, it can be seen from the figure that the synthesized silver nanoflower is relatively uniform.
