I have dissolved PVP and AgNO3 in EG for the synthesis of silver nanowire. PVP is used as capping agent and Ethylene Glycol as reducing agent. AgNO3 as source of silver. Different salts were used for the synthesis of silver nanowire.
After the synthesis of silver nanowire uv visible test is used to check the status of silver nanowire synthesized. I have attached the graph of UV visible spectrum help me to find out about the braid peaks of spectrum
Dear Anam Bashir,
Silver Nanowires should have a peak that is around 400 nm and a shoulder a bit lower (360 nm), I see you have those in your spectra. What I don't understand is the peaks you are referring to? Below 300 nm? Or above 400 nm?
The signal below 300 nm looks strange, it should go up also its scatter is worrying, seems an instrumental or procedural error rather than something in your material. I would run the spectra again with special care to record good baseline scans, this could be the culprit.
The signal above 400 nm is Mie Scattering caused by the Nanowires. This is explained in this excellent article: Article Synthesis and UV–vis spectroscopic study of silver nanoparti...
Hope this helps, kind regards, Leo
You need to make sure your cuvette and solvent are transparent in the region of interest.
