dc.description.abstractIn this research, the effect of gamma ray doses on volatile organic compound (VOC) sensing properties of Cu doped TiO 2 nanoparticles are studied to further improve the VOC sensing performance. Pure and Cu doped TiO 2 nanoparticles have been prepared by sol -gel technique on Au interdigitated plexiglas substrate and irradiated by gamma-rays with doses varying from 1 to 150 KGy. The irradiation was performed by using 60 Co as gamma source. The structural, morphology and modifications were analyzed with X-ray diffraction (XRD), scanning electron microscopy (SEM), and Atomic Force Microscopy (AFM) techniques. The sensing performance of these films toward ethanol, methanol, 2 -propanol, benzene, toluene, xylene and ammonia vapors has been tested. It was observed that no remarkable sensor response to any vapors except ammonia was observed at room temperature. Changes in sensor ' ammonia sensitivity have been correlated with the gamma radiation dose and Cu doping ratio. Maximum sensing performance was observed with 3% Cu doped TiO 2 exposed to gamma radiation dose of 150 kGy.
