Dear Sachin,

probably I cannot help you, but I observed unwanted AgS films and perhaps we can learn from it. If you have a silver spoon, then you can observe that it colours black due to SO2 in the atmosphere. I observed that silver nanowires dissolved in air due to contact with unclean air (acid humidity). Perhaps you can do the following:

Evaporate your glass substrate with silver (eventually still a contact layer between glass and silver). Then you must build a small reactor - a tube, where you put your sample. You need an inlet for SO2-gas. (You burn sulfur like the old alchemists). But you must clean work. Eventually you must heat the substrate to increase the reactivity.

This is my proposal.

With Regard

Dear Sachin Padwal, great care when working with chemicals prone to oxidation, degassing and inert gas blancket are needed. Details in the following links. My Regards

Thanks to all for your replies.I finally deposited AgS films with some other molarity concentration using same sodium thiosulphate.It took 8 hrs at room temperature for deposition but films are very good.Thank you once again to all.

This is correct for the liquid electrolyte, what about the behavior of the polymer electrolyte?
