The science of nanomaterials has created great excitement and expectation in the last decade at the nanoscale fundamental properties changes for example a nanoscale wire or circuit component does not necessarily obey ohm’s law when we reach nanoscale everything will be change, including gold’s color, melting point and chemical proper- ties [1]. Oxide nanomaterials used as catalysts and starting materials for preparing advanced structural ceramics [2]. CdO an important n-type semiconductor with a direct band gap of 2.5 eV and an indirect band gap of 1.98 eV, has promising applications in catalyst sensors, nonlinear materials, solar cells, and other optoelectronic devices etc [2-4]. Cadmium oxide (CdO) nanoparticles were prepared strating from Organic CdI2 complex through simple calcination step at 600 oC, the obtained product are analyzed by SEM, TEM, TG/DTA, IR, and X-ray diffractometer (XRD), the average size of CdO nanoparticles found to be 50 nm [5].
