Schematic illustration of the proposed mechanism for the formation of Ag NFs.

(A–D) SEM images of Ag NFs grown at the reaction times of 1 s (A), 2 s (B), 3 s (C), and 5 s (D) when the concentration of AgNO3, PVP, CA, and ascorbic acid in reaction solution are 38, 38, 1.9, and 38 mm, respectively. (E) Schematic illustration of the proposed mechanism for the formation of Ag NFs in four main stages.
