I am synthesizing the ZnO seed layer using Zinc Acetate dihydrate sol.+ NaOH followed by stirring at 60degrees for 2 hours. But, I am not able to understand the mechanism. How one can tune particle size? What is the role of NaOH ?
Zinc acetate reacts with sodium hydroxide to synthesize zinc oxide.
Zn(NO3)2 + 2NaOН = Zn(OH)2 осадок + 2NaNO3
I hope this is clear?
Next, to control the size of the nanoparticles, you need to change the temperature and deposition time. According to the literature, you can try from 60 degrees to 200.
