• studied by varying the gas concentration. The developed GO-Cs sensor shows a higher response to NO2 than the pristine GO based sensor due to the oxygen functional groups. The detection limit measured with GO-Cs sensor is ≈90 ppb. Keywords: caesium; conductometric; doping; drop casting; gas sensor

• polyvinylidene fluoride membrane (0.2 μm). The precipitate was then added to water (30 mL) and filtered. The process was repeated twice to obtain dark solid GO-Cs. Finally, the gas sensors were fabricated by drop casting of the prepared GO and GO-Cs materials onto 2 × 2 mm2 transducers and then they were placed

Thin films deposition techniques such as drop-casting [17], screen printing [18], and ink jet printing [19], are currently used to fabricate electronic devices on great variety of substrates, either rigid or flexible, looking

Drop-casting offers a cost efficient production of photovoltaic semiconductor thin films. Nevertheless, depending on the
