Influence of Ball Milling on CdO Nanoparticles Prepared By Thermal Decomposition

Cadmium oxide has found its applications in various areas of research such as solar cells, phototransistors, photodiodes, transparent electrodes and gas sensors. In the present work CdO nano particles were successfully synthesized from cadmium acetate through thermal decomposition at high temperatures by adopting the solid state reaction. The prepared nano particles are subjected to ball milling for different timings. From X-ray diffraction it was found that the particle size decreases for an increase in the time of ball milling. The structure and the elemental composition were analyzed using SEM with EDAX. The optical band gap of CdO nano particles were determined using UV-Vis absorption spectroscopy. The thermal properties were determined using TGA/DTA analysis.
