| Abstract | ||||
| Surface plasmon resonance (SPR) based sensors using Ag thin films have been successfully applied for detection of nitrogen dioxide (NO2) gas. The SPR sensors have Cobalt Phthalocyanine (Co-Pc) as active add layer. Surface plasmon was generated via a prism coupler in Kretschmann configuration. It is found that the sensitivity of SPR sensor is 0.14 ppm in ambient environment at NTP. The simple structure of the SPR sensor makes it superior to liquid chemical sensors for the detection of NO2. | ||||
