Producing High Purity of Metal Oxide Nano Structural Using Simple Chemical Method

Calcium oxide nanoparticles and nanorods were prepared by using chemical method at two Molarities. The field emission scanning electron microscopy (FESEM) images suggested the formation of nanoparticles (50-60) nm and nanorods with diameter about 500 nm and length 3μm. The average surface roughness of CaO thin film was imaged by carried out atomic force microscope (AFM) and roughness found to be between (3.52-5.46) nm. XRD patterns show that the CaO was cubic crystalline nature and average grain size was found to be 70 nm. The direct optical band energy gap of all conditions to be ranged between (3.5-3.7) eV and thermal gravimetric analysis (TGA) was studied. Photoluminescence (PL) properties were investigated and founding two emission bands.
