Influence of precursor solution volume on the optical properties of spray deposited ZnO films

Résumé

In this contribution we present the optical properties of ZnO films prepared by spray pyrolysis on glass substrate growth at 350°C with various precursor solution volumes. Optical characterization of ZnO films was carried out by transmittance measurement. The optical transmittance spectrum for the film deposited at low precursor solution volume exhibits high transparency with a decrease when the precursor solution volume increases. It is found that the optical band gap decreases from 3.30 to 3.27 eV and the optical constants increase with the increase of the thickness of the films attributed to the increase in lattice defects.
