- W2031271802 abstract "Undoped and noble metal-doped very thin SnO2 sensing layers deposited by the pulsed laser ablation (PLA) technique upon micromachined Si substrate heater elements have been extensively characterised. The main objective behind the effort carried out in this work has been the challenging perspective to define a sensing layer technology and a sensor operating mode (continuous (DC) vs. pulsed temperature (PT) mode) which allows the long term measuring and the easy discrimination of very low concentration of benzene by an interfering species like carbon monoxide, both present in the outdoor air. The experimental results reported in this work have shown that combining the sensor technology with a suitable catalytic element (in the present case, gold) and a proper sensor operating mode, very low concentration of benzene can be revealed with a sufficient selectivity towards CO. One of the major problems encountered during the long term test of the sensors has been the loss of the sensitivity to benzene with the time. An attempt has been made to explain the reason of this experimental result. We firmly believe that many factors contribute to it. Among them, the annealing of point defects associated with the oxygen vacancies as well as the loss of the catalytic efficiency by the added Au layer as effect of a possible coalescence of the metal clusters at the sensor working temperature (T≅400°C). To partially reduce the cluster mobility and to preserve the benzene sensitivity, the last assumption would suggest to operate the sensors, no matter if in DC or in PT mode, at a temperature lower than that used in this work." @default.
