With the help of electron beam evaporation of mechanical mixtures of non-magnetic micron powders ZnO and carbon in vacuum with the subsequent annealing of evaporation products on air at the temperature of 773 K, single-phase crystal nanopowders ZnO-C were produced with the hexagonal wurtzite structure and low content of the carbon dopant not exceeding 0.25 wt. %. It is established that the doping ZnO with carbon stimulates primary growth of nanoparticles along the direction <0001> in the coatings, which are formed at deposition of nanoparticles on cold glass substrates, it means that nanocrystals growth in coatings occurs in the same way as crystals growth in thin films, with growth anisotropy in the c- axis direction in wurtzite ZnO. Change of morphology of coatings on the basis of ZnO by doping as a consequence of size change of the globule of the average size correlates well with the parameters of their specific surface area and change of the grains size from XRD data. Element mapping has confirmed homogeneous distribution of carbon in ZnO lattice when using the method of pulsed electron beam evaporation of powders mechanical mixtures.
