| Abstract: | Theoretical calculation on the phonon dispersion of CdO nanoparticles at room temperature is reported here for the first time. The mean square amplitude, Debye–Waller factor and Debye temperature are calculated for CdO nanoparticles from the phonon spectrum and compared with the experimental results obtained from Rietveld refinement of XRD pattern of the CdO nanoparticles. The thermal stability of the nanoparticles is studied from both the experimental and theoretical calculations of melting point which is found to be 3686 K and 3951 K, respectively, greater than that of bulk CdO.
