SPECTROCHIMICA ACTA PART A-MOLECULAR AND BIOMOLECULAR SPECTROSCOPY, vol.286, 2023 (SCI-Expanded)
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 Zr-C bonds before and after gamma irradiation were explained by the corresponding wavenumbers in the infrared (IR) absorption spectra. Simultaneously, the stretching vibration of the Zr-O-C bonds are explained by the effect of gamma radiation and the corresponding wavenumbers. Surface activity of ZrC nano -particles increased as a result of gamma irradiation and this increasing directly affected to the intensity of infrared peaks, which is characterized the C-OH groups and C-O 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.
