Metal oxide gas sensors: development and characterization
In this review, a number of oxide materials deposited on optical fibers have been studied to determine the most optimum materials for the production of optical sensors intended for the detection of petroleum gases, namely, butane, ammonia, and ethanol. The sensory properties of oxides materials, suc...

In this review, a number of oxide materials deposited on optical fibers have been studied to determine the most optimum materials for the production of optical sensors intended for the detection of petroleum gases, namely, butane, ammonia, and ethanol.

First, the magnetron sputtering of zinc oxide and titanium dioxide have been described; second, the results of a study of the morphology and sensing characteristics of the optical fiber sensors have been discussed. The fabrication route of liquid petroleum gas (LPG) optical sensors based on optical fibers coated with ZnO, TiO2, and SnO2 nanocrystalline films has been analyzed.
