The paper analyzes the influence of the type of carrier gas: helium, air, nitrogen on the physical properties of nanopowders of ZnO and ZnO : Mn, synthesized by ultrasonic spray pyrolysis. It has been investigated the surface morphology of samples, their crystal quality and EPR spectra, conducted X-ray analysis. Turn aut the effect of heat treatment on the properties of nanocrystals. It is shown that nanopwders ZnO : Mn, synthesized in a nitrogen atmosphere, may be have the p-type conductivity.
