Fig. 4 Variation of S and W parameters of samples with nanocrystallite size
4 Conclusion
An understanding of size variation of cadmium oxide nanoparticles influences the
crystal structure and defect characteristics have been studied in this report. Besides,
the results of X-ray diffraction measurements and TEM studies are also reported.
These showed lattice constant variation in one direction and similar shape and sharp
lattice fringes. The positron annihilation spectroscopy showed the peak shift in lower
momentum direction for 9 and 17.5 nm samples and toward higher momentum
direction for 22 nm sample. In summary, the size variation successfully shows the
agglomeration of defects.
