To deposit silver or gold film of nanometer thickness, we need an expensive Vacuum coating machine. Since such expensive machines cannot be afforded everywhere, how can one deposit silver or gold film of nanometer thickness on a glass prism or glass slides? I mean to say that is there any chemical route available?
For SPR studies is it needed to cover entire substrate, why can't we just disperse it in a liquid and spin coat. In our lab they do in this way for studying gold SPR ...
But how can you get a gold liquid or silver liquid to dip the substrate? Means how can you get a gold or silver in liquid form?
You can try special solutions or make it self. For example http://www.aspol.info/products/silvering/silvering-liquid.html
How it works (see from 2 min) https://www.youtube.com/watch?v=aXM-WcGXyKw
Thank you very much for the supporting information on special solutions. I will definitely try that.

Here is another reference, a step-by-step procedure for producing a silver mirror on glass:

By controlling the time you will be able to control the thickness.
Hello Sibashish ,
As far as your lab facility restriction concerned, I will suggest you to send your proposal to INUP facility. I am using it at IIT Bombay . Pl refer to IITB site .
Good Luck !
