Implication

Experimental investigation demonstrates light-controlled synthesis of near-infrared-absorbing silver nanoprisms from colloidal seeds, indicating scalable tuning for optical communications.

Key Points

Synthesize silver nanoprisms exhibiting strong near-infrared plasmon resonance at optical communication wavelengths using a modified photoinduced growth method.
Illuminated preformed silver seed colloids using low-intensity light-emitting diodes and color-filtered white light across distinct wavelength bands.
Characterized particle morphology and crystal structure using scanning electron microscopy, high-resolution transmission electron microscopy, and electron diffraction.
Performed time-resolved monitoring to analyze the consumption of precursor seeds and the dimensional evolution of the nanoprisms.
Lateral dimensions of the silver nanoprisms correlated quasilinearly with the illumination wavelength and the main in-plane dipole plasmon band position.
Structural characterization revealed flat, single-crystal face-centered-cubic architectures across the synthesized nanoprisms.
Time-resolved analyses indicated steady precursor seed consumption with minimal aspect-ratio variation after a brief initial induction period.
