“…Additionally, the Scherrer method was used to find the crystallite size of NO, MNO and CMNO through the following expression. 41 D = (0.9 λ )/( β cos θ )where θ is Bragg's reflection angle, β represents FWHM and λ is the wavelength of X-ray radiation (0.15406 nm for CuKα). The calculated values of crystallite size D for NO, MN and CMNO are 59.77, 47.45, and 41.24 nm, respectively.…”
