These films are polycrystalline with a c-axis preferential orientation parallel to the substrate. The films present a resistivity that varies from 5.0 × 104 Ω cm to 1.0 × 109 Ω cm with an optical visible transmittance of 85%. The sensor response exceeds more than five orders of magnitude when exposed to UV light recovering to the initial state in the presence of ozone. © 2006 Elsevier B.V. All rights reserved.&lt;/p&gt;
