- Opis:
- Composite cadmium oxides-zinc oxides, $(CdO)_{x}(ZnO)_{1 - x}$, thin films are grown with variable composition, x, by non-conventional spray pyrolysis technique from two separate cavities. X-ray diffraction proves the formation of cadmium and zinc peroxides upon deposition. Further annealing in air causes a loss of crystallographic order in zinc oxide grains. Annealing does not affect the structure of cadmium peroxide. The optical constants are estimated by the Murmann exact equation from transmittance and reflectance in the wavelength range between 400 and 2400 nm and show normal dispersion. Highest luminescent yield is assigned for samples with composition x = 0.5. Annealing causes increase in luminescence yield of $(CdO)_{x}(ZnO)_{1 - x}$ films that could be explained in the framework of structural change.
