Abstract

Zinc oxide (ZnO) is one of the most studied materials in nanoscience and chemical sensing research area. Monitoring the variations of electrical conductance of different ZnO nanostructure has enabled the detection of different gases and volatile organic compounds (VOCs). Another interesting perspective emerges from the development of optical sensors and experiments based on the photoluminescence of the semiconductor, has shown excellent sensing properties towards different chemical substances, ranging from oxygen, NO2, CO and volatile compounds (ethanol, H2S), to biomolecules, such as glucose, in aqueous solutions. In the present study ZnO has been investigated as optical sensing material towards ozone (O3) detection, by monitoring its laser induced room temperature photoluminescence (PL) emission. The optical material consists of ZnO/polymer nanohybrids (ZnO/poly(poly(ethylene glycol) methyl ether methacrylate) (ZnO/PPEGMA) and ZnO/polydimethylsiloxane (ZnΟ)/PDMS)) which are excited with a UV pulsed laser source (λex= 248 nm, τex= 15 ns). The performance of these sensing systems has been investigated with respect to response, reversibility, and dynamic characteristics (response/recovery time) as a function of ozone concentration in synthetic air (1600 down to 50 ppb).
