OFET based H2S gas sensing among reducing and mining gases using green synthesis SnO2

In this paper we present detection of H
₂
S gas using an organic field effect transistor (OFET) based sensor. A low-cost green synthesis process for SnO
₂
nanoparticles and bi-layer approach for device fabrication have been adopted to come up with the sensor. With the help of multiparameteric analysis, selectivity towards H
₂
S gas was proved among other reducing and mining gases.
