摘要：
Experimental results show that the use of film-forming solutions based on zinc and aluminum nitrates and high molecular polyvinylpyrrolidone allows obtaining thin oxide coatings having unusually large bandgap values and transparent in a wide spectral range. The values of the bandgaps of coating materials are significantly higher than the bandgap of bulk ZnO, and it is varied in the range from 3.46 to 4.16 eV, resulting from the metastable structure of the coating.
