Hello,
I need at least 60 nm of a gold layer on top of silica beads in varying sizes from 0.4 - 5.0 µm. I could achieve very thin layers of gold.
How could I get thicker layers?
Thank you
Have you examined higher concentration of gold precursor?One expect thiker layer of gold will form.
You could use a TEM grid coater which often have gold targets in them (for sputtering), and agitate the beads during deposition to ensure an even coating.
Dear Sven,
you can easily achieve the coating of 60 nm thin layer of continuous film of gold by e-beam evaporation.
Good luck.
TH.
