Abstract

The paper discusses the issues related to the influence of technological conditions of synthesis by ultrasonic spray pyrolysis on the size and lattice parameters of ZnO:Mn nanocrystals. It is found that, depending on the concentration of zinc nitrate in the base solution from 5% to 10%, the synthesized nanocrystals have sizes ranging from 36÷40 nm for small solution droplets and 51÷55 nm for large droplets, respectively. Based on the X-ray diffraction data, it is found that the nanocrystals of small sizes have a more perfect crystal structure with a small number of intrinsic defects compared to the nanocrystals of larger sizes.
