Abstract
Zn1-xCoxO nanopowders were obtained by chemical bath deposition followed by thermal annealing. The structure and morphology of the samples were studied by X-ray diffraction analysis and scanning electron microscopy. Raman spectra were studied at room temperature using a Solver Spectrum (NT-MDT) spectrometer with laser excitation at 473 nm. Optical spectra in the range 300-800 nm were measured on a Lambda 35 PerkinElmer optical spectrophotometer. Depending on the synthesis conditions, nanopowders with an average size of 1-2 nm were obtained.
