Abstract
A process for the preparation of nano zinc oxide particles is disclosed. The process comprises of dissolving a zinc metal precursor in a solvent to obtain a first solution and dissolving a base in an alcohol to obtain an alkali solution. The alkali solution is then added to the first solution over a predetermined period of time to obtain nano zinc oxide particles in solution.
