3.1.1. XRD pattern
Scherrer equation that illustrated in equation 1, was used to determine
the average particle size of cadmium oxide nanoparticles.
D = (094 λ) / (β cosθ)……………. (1)
Where λ = 1.542 Å, β FWHM in radians and θ is the diffraction position.
The (111), (200), (220), (311) and (222) reflections were determined in
the XRD measurement and the result are in agreement with reference
patterns of CdO (JCPDS file No. 05-0640) [15]. See Figure 1.
