Study of Optical behavior of nanocoposites (MgFe2O4/CNTs) and the effect of temperature on these Optical properties

In this research, MgFe2O4/CNTs was prepared by coprecipition method. The sample was calcinated in temperature range of 400℃-800℃. Calcinated powder phases was determined by X-ray diffraction method and the crystals size mean by sherer formula. The surface morphologies of the nanoparticle were characterized by scanning electron microscopy SEM. Optical properties was measured by UV-Visible spectroscopy in the range of200-1000nm. The result showed Increasing calsinate temperiture can leads to bigger nanoparticle and by increasing temperature the emount of energy band gap is reduced
