A study was conducted on obtaining powders for microwave dielectrics from zinc oxide using deep eutectic solvents. As a result of using various solvents, a monophase ZnO powder is formed, the particle size and phase composition of which can be controlled by changing the calcination temperature. Deep eutectic solvents make it possible to obtain zinc oxide precursors by interacting the corresponding deep eutectic solvent with water, without using alkalis or ammonium hydroxide, which gives reason to consider such synthesis more environmentally friendly. Zinc nanoparticles obtained at 500 °C have a pronounced antimicrobial effect on Staphylococcus aureus (S. aureus) and Escherichia coli (E. coli).
