You can also make MoOx precursor solution using Ammonium Molybidate tetra hydrate dissolved in DI water according to your requirement. Then heat the coated film around 250C and after decomposition- MoOx film is formed.
Maria Vasilopoulou Hey I got a paper where they follow similar procedure to prepare MoO3 solution like you did. But they also used 2 methoxy ethanol along with PEG. I need to make MoO3 coating solution. Do you think I can go ahead with your procedure without using 2 methoxy ethanol?
Mohammed Asrar Ul Haq I don't know what you mean by moist MoO3. It is already mentioned above that MoO3 can be dissolved in H2O2. Also, MoO3 can be dissolved in a 1 M NaOH solution.
