- •
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.
