Zusammenfassung:In this research, the effect of gamma ray doses on volatile organic compound (VOC) sensing properties of Cu doped TiO2 nanoparticles are studied to further improve the VOC sensing performance. Pure and Cu doped TiO2 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 60Co 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 TiO2 exposed to gamma radiation dose of 150 kGy. •Highly selective sensing of ammonia can be achieved by using Cu doped TiO2.•Ammonia sensing performance of Cu doped TiO2 can be controlled by the doping ratio.•The influence of gamma ray dose on the ammonia sensing performance.•Ammonia sensing performance of Cu-doped TiO2 can be significantly improved with gamma radiation dose.
