Abstract

In this novel work, we have studied the optical properties of CuBaM-CZFO nanocomposites. (Cu0.5Ba0.5Fe12O19)1-x/ (Co0.6Zn0.4 Fe2O4) x [where x=0.1,0.2] nanocomposites were synthesized individually by sol-gel citrate method and then made into nanocomposites by physical mixing technique. Further characterization over their structural, morphological and optical properties were carried out in detail. With the help of UV analysis, the optical properties such as, the band gap energy was discovered which is found using Tauc’s plot. The bandgap energy is 2.6503eV for CuBaM-CZFO 90-10 which is lesser than CuBaM-CZFO 80-20 (2.8456eV). The structural, morphological and optical properties of novel CuBaM-CZFO nanocomposite are reported and compared with, both among themselves and from the literature review.
