Is it possible to generate the LSPR effect with sunlight, or is high intense laser light required? Is the incidence angle dependent on plasmonic generation?
Dear Nicolo,
I think, color of the metallic nanoparticle is due to the light absorption or scattering at particular wavelength. This absorption or scattering is by the LSPR effect. So my question is that, How the LSPR effect leads to the light absorption or scattering of the metallic nanoparticle?
Another one is, whenever the dielectric constant matching condition is occurred the effect will generate?
This effect is possible in all metals. Why it is favor in noble metals?
Dear Nicolo,
Can you explain how the LSPR and absorption/scaterring is related? What is the physics behind it?
if your LSPR is in the UV-blue region you get more absorption than scattering, but if you are in the yellow-red (or even IR) region
How can understand whether the LSPR in UV or in IR. If it is in UV-blue, why absorption is higher?
if you have gold you get a narrow and intense resonance (low absorption), if you use a transition metal like nickel you will get a broad and low intense resonance (high absorption)
Why the intense and narrow resonance generate low absorption?
Very interesting and useful discussion.
thanks to dear Nicolò Maccaferri
