摘要：

This paper reports the study on the shape effect of gold nanoparticles on their plasmonic responses to the vapor samples, such as methanol, ethanol and propanol. In typical process, it was observed that the plasmonic of gold nanoparticles was very sensitive to the presences of the vapor samples by giving the change in the absorption as well as the shift in the SPR peaks position. It was also found that the plasmonic responses to the vapor indicated a significant improved if the gold nanoparticles prepared in the form of nanorods morphology. The plasmonic response of the spherical and nanorods gold nanoparicles to the gasses will be discussed.
