ABSTRACT
In this work , the NiCoFeONanoparticles ferrites (where x= 0.0, 0.2, 0.4,0.6 and 0.8)
were Synthesized using co-precipitation method. The investigation of structural and optical
properties was carried out for the synthesized samples using X-ray diffractometer
(XRD),Fourier transform infrared spectrometer (FTIR ) and Ultraviolet visible
spectrophotometer(UV – Vis) .XRD revealed that the structure of these nanoparticles is cubic
spinel structure with crystal size 9.44 - 5.75 nm .Lattice parameter was found to be 7.5Aᵒ
.FTIR spectroscopy confirmed the formation of spinal ferrite by showing the characteristics
absorption band around 3123, 1620 , 1403 , 530 , and 419 . the energy band gap was
calculated using UV-VIS spectrophotometer and was found to be 5.13,4.88, 4.82 , 4.79 ,
and 4.58eV respectively; these results confirm that the subsistance is an insulator
