Development of film sensors based on ZnO nanoparticles for amine gas detection

► A novel ZnO fluorescent film was fabricated by a clean, very easy pathway method. ► The glass slide is the promising substrate for the deposition of ZnO particles. ► There are almost uniformly distributed nano-particles on the surface of the substrates. ► The film is selectively sensitive to the presence of amine and the detection limit for amine gas is calculated 162.0 ppm.
