Dear Scott,
Thank you for your letter, I have been working on the optical properties of Au-Cu2O core-shell nanoparticles. In my research, the SPR peak of the Au nanocores undergoes a red shift further to longer wavelengths of 599, 605, 616 and 638 nm as the thickness of Cu2O shell increases respectively to 9, 15, 17, 20 and 25 nm. however, I have some problems finding a suitable theoretical model to describe our experimental data. It would be really nice if you could help me built FDTD model of SPR of Au-Cu2O core-shell nanoparticles.
We are looking forward to hearing from you soon.
Kind regards,
Doanh,
