Studies of Zinc Oxide and Zinc Phosphate Nanostructures

open access: yes, 2020
In the framework of this dissertation, a microwave-assisted synthesis strategy for the production of zinc oxide nanoparticles, at the lower end of the nanoscale, is presented. The radius of these spherical particles can be adjusted by choosing a reaction temperature between 125 °C and 200 °C in the range of 2.6 nm to 3.8 nm.
