“…At the lower concentration of citrate (⩽5.0 Â 10 À4 M), silver nanoprisms are converted into nanodecahedrons silver by increasing the concentration of citrate as shown in Figure 12. Although the intensity of light affects the shape of the NPs, the lighting power density did not influence the shape conversion except for reaction rate [100].

“…Since the concentration of the capping agent is one of the factors controlling the shape conversion of AgNPs [8], a formation of different-shaped AgNPs was monitored in the reactions containing different DNA amounts (10-40 mg) under a blue LED irradiation for 24 h. As seen in Figure 2(A), the reaction containing 10 mg DNA could induce a formation of spherical AgNPs but not for a shape-conversion as indicated by the remained yellow colour and the characteristic SPR peak at 413 nm [30]. In contrast, the increased DNA amount to 20 mg was sufficient for inducing the formation of nonspherical AgNPs as determined by the changed colour to green and the characteristic SPR peaks at 412 and 595 nm, which corresponded to the in-plane dipole plasmon resonance of possibly formed hexagonal and triangle AgNPs [32].…”

“…The photo-induction process has received the increasing interest as a simple, effective approach to mediate a formation of different-shaped AgNPs [8]. Several light sources, including fluorescent light, UV light, light emitting diodes (LEDs), laser and sunlight, were reported to drive the photo-reduction of metal salts and induce the growth of metal seeds into anisotropic shapes [8][9][10][11][12][13]. The shape conversion direction of AgNPs was proposed to greatly depend on the excitation wavelength of a specific plasmon.…”

“…Thus far, several technologies including seeded growth and template methods have been developed to controllably synthesize metal particles with special morphology [18][19][20]. Among them, seeded growth involving preferential growth on preformed seed surface is probably the most widely used and effective protocol because of its advantages in structural control and variety [21,22]. However, despite its importance, the development of seeded growth for metal particle has remained a considerable challenge to achieve micron metal particles with desired structure.…”
