NOVELTY - The present study is related to a ternary polymer composite with N-doped GQD intermediate layer for ammonia gas detection. The Indium oxide fibers were fabricated by electrospinning and an optical ratio of indium oxide fibers and polyaniline for detecting ammonia gas was found. By introducing N-doped GQD as an intermediate layer, the present study can improve the electronic conduction of p-n interface of the original type semiconductor polyaniline and n-type semiconductor indium oxide fiber. The N-doped GQD intermediate layer as a modified layer between polyaniline and indium oxide fiber is able to improve the sensibility and response of the ammonia gas detection.
