Rezumat

The paper is divided into two main sections: first, we report on magnetron sputtering of zinc oxide and titanium dioxide; second, the results of the investigation of the morphology and sensing characteristics of the optical fiber sensors are presented and discussed. We describe the fabrication route of the liquid petroleum gas (LPG) optical sensors, based on optical fiber coated with ZnO and TiO2 nanacrystalline films. The obtained sensors attain 2.77% sensitivity for ZnO and 24.4% for TiO2.
