Structural properties of ZnO:Al films produced by the sol–gel technique
- 70 Downloads
ZnO:Al films are produced by sol–gel deposition at temperatures of 350–550°C, using different types of reagents. Atomic-force microscopy, X-ray diffraction analysis, Raman spectroscopy, and optical transmittance measurements are used to study the dependence of the structural, morphological, and optical properties of the ZnO:Al coatings on the conditions of deposition. The optical conditions for the production of ZnO:Al layers with preferred orientation in the  direction and distinguished by small surface roughness are established. The layers produced in the study possess optical transmittance at a level of up to 95% in a wide spectral range and can be used in optoelectronic devices.
