Abstract

A room-temperature nitric oxide (NO) gas sensor is prepared by using electrochemical synthesis of conducting polymer, poly-(3,4-ethylene dioxythiophene) (PEDOT) and characterized by surface plasmon resonance (SPR) method. Guided by SPR angle simulation, the optimal thickness of deposited PEDOT thin film is 25 nm and the resultant lowest detection limit of NO is 8 ppm. It exhibits 1.3 times higher responses to 25 ppm of NO gas than NO2.
