What accounts for absorption LSPR shifting to shorter wavelength regions over EM spectrum with increasing metal nanosphere size?

03 March 2019 1 8K Report

I have read about the absorption peak shifting to longer wavelength regions for semiconductors because with increasing size of the nanoparticle, the bandgap energy decreases and hence increases the wavelength due to the following relation

E= hc/(wavelength)

Hello Akanksha Bhardwaj ,

I would suggest checking section 1.1 of the following review paper:

Article Localized Surface Plasmon Resonance as a Biosensing Platform...

It also discusses the narrowing and broadening of the spectra in relation to the size.

Kind regards,

Jules

Physical significance or fundamental of two dipole LSPR peaks appearing for single core-shell nanostructures?

I need basic explanation for the appearance of two dipole resonance peaks at different wavelengths, one peak is attributed to the effect of core material and other peak due to shell material.
