Deformation stresses in ZnO:Mn nanocrystals

Two groups of ZnO and ZnO:Mn nanocrystals doped with Mn 2, 4, and 8 at.% using a zinc nitrate solution with a concentration of 5% and 10% were obtained by ultrasonic aerosol pyrolysis. By X-ray diffraction analysis, it was found that a decrease in the concentration of the initial solution leads to a decrease in the strain stresses in the crystal lattice of nanocrystals. This also improves the doping processand reduces the size of the nanocrystals. During the doping of ZnO nanocrystals with Mn impurity, strain stresses increase more intensively in nanocrystals obtained from a 10% zinc nitrate solution.
