Control and modulate the shape of silver nanoparticles via chemical etching and photochemical regrowth process.
Tune the LSPR properties by adjusting the excitation wavelength during photochemical regrowth process.
The LSPR properties of silver nanoparticles are tuned in range from 490 to 800 nm.
Both modulation of shape and LSPR properties of silver nanoparticles during photochemical regrowth process are excitation wavelength dependent.
