I am working on V2O5 (vanadium Pentoxide) thin film growth by spin coating. I am following the process for synthesis of V2O5 solution as mentioned in the reference articles. Even after doing exactly as they are mentioned in the articles, I am not getting sol gel required for spin coating.
I am using V2O5 powder (98%) for making sol-gel.
The process says 0.3 grams of V2O5 powder + 30 ml of 30% H2O2 (Hydrogen peroxide) and vigorous stirring until a red-brown viscous liquid/sol-gel is obtained. and upon aging, the viscosity increases.
I have followed exactly as mentioned but I am not getting the viscosity required for spin coating. It is just an aqueous solution with consistency of water.
Should I be adding any gelling agent or anything else?
Any hekp in this regard would be helpful
