Hi.
I am studying the plasmonic effects of gold nanoparticles on a substrate (TiO2) and have successfully used the Scatterer on Substrate model to do this. I am able to produce an absorption spectrum with the nanoparticle present however I also want to be able to compare this spectra with one without the nanoparticle. I tried using the same technique whereby I create a volume within the substrate (100x100x20nm), set up a integration over this volume, and then used the formula:
Integration_volume(emw.Qh)/Power_In
The results I get from this however are tiny e-33 and fluctutate around zero even within UV regions where I would have expected some absorption by the TiO2. Has anyone had experience in doing this and can tell me where I am going wrong?
Many Thanks,
Josh
