Inorganic-organic hybrid materials exhibit a vast application potential due to their tailorable mechanical and optical properties. These hybrid materials are hi-tech and sometime show unexpected properties different from organic/inorganic molecule. In the present study, the nanosized Ce-Fe composites of perovskite structure were synthesized via sol-gel method using mixture of hybrid materials, i.e. polyvinyl alcohol (PVA) and cerium nitrate, and calcined at different temperatures. The as-synthesized Ce-Fe composites were characterized using XRD, SEM, FTIR, UV-Vis techniques to study their structural, morphological and optical properties. Characterization study shows crystalline nature of particles with a size ranging from 22.04 nm to 57.73 nm with agglomeration and porous nature. These composites show the characteristic metal-oxygen absorption band in wavelength range of 500-400 cm – 1 and band gap energies from 4.0 to 5.2 eV. The formation of Ce-Fe composite material is reported at calcination temperature of 800-1000 (C. Further calcination at a higher temperature may lead to the formation of CeFeO3 which offers scope of further study.
