摘要：

The present work is concerned on developing a high performance and reliable SnO(2)-based gas sensor to detect HCHO and NO(2) gas for indoor environmental monitoring. The sensors were fabricated with the radio-frequency induction plasma deposition (IPD) method. SEM (Scanning Electron Microscope) and XRD (X-Ray Diffraction) method were used to examine the physical properties of the sensing films. The obtained sensors showed high sensitivities to HCHO and NO(2) gas at extremely low concentration 20 ppb (parts-per-billion) with rapid response and recovery time less than several minutes. Finally, the temperature dependency of the sensors was described in the paper. The results indicated that the fabricated sensors are promising for monitoring indoor air pollution.
