Prior to observe under TEM, I want to get an idea about the shape of the Au nanoparticles according to the absorption spectra. Can anyone help me out?
Thank you
If you want anyone to help you, you will have to provide: -a correctly labelled spectrum. Right now this might be vibrational absorption in which case the "Axis Title" might either be cm-1 or THz while it would also be possible to be electronic/plasmon excitation in which case the units would be nm -at least a rough idea about your nanoparticles: ligand saturated/pure gold assumed/measured in solution/dry measurement/...
Yes these are plasmon peaks of seed mediated synthesis Au nanoparticles. X-axis represents wavelength and Y-axis represents optical density (OD)
In this case Au nanoparticles may be in nanorod shape. Where one can get clear two peak in this spectral band. Broadening in peaks indicates the large size of nanoparticles. Some other shape may also be interacting.
That's what I wrote, it could be mixture of varied particles shapes and sizes
Broad peaks indicate the existence of either different shapes or large size distribution..
You can indicate your method to allow other people helping you.
