FTIR spectroscopy of ZrC nanoparticles under the gamma radiation

Abstract

In the presented work, infrared spectra of nano-ZrC samples were taken in the range of 400–4000 cm−1 of the wavenumbers before and after gamma irradiation (5 Mrad, 15 Mrad, 50 Mrad and 150 Mrad). As a result of the spectral analysis, it is possible to notice that seven IR bands appear in the general approach before irradiation. The peaks explaining the vibration of the ZrC bonds before and after gamma irradiation were explained by the corresponding wavenumbers in the infrared (IR) absorption spectra. Simultaneously, the stretching vibration of the ZrOC bonds are explained by the effect of gamma radiation and the corresponding wavenumbers. Surface activity of ZrC nanoparticles increased as a result of gamma irradiation and this increasing directly affected to the intensity of infrared peaks, which is characterized the COH groups and CO asymmetric stretching vibration. At the relatively high doses, such as 50 Mrad and 150 Mrad, the state of amorphization in nanomaterials is explained by the corresponding spectra.
