The special optical properties of metal oxide nanoparticles are the most considered properties of these particles in optical applications and electronic devices. In this research, at first magnetite nanoparticles with 31, 27, 25, 23 and 19 nanometer sizes were synthesized by modified co-precipitation method in presence of an external magnetic field and then their direct and indirect band gaps were calculated. As the results showed, with increasing the intensity of magnetic field and decreasing of nanoparticles sizes, direct and indirect band gaps have increased, that is due to the quantum limit which is originated from changing in nanoparticles sizes.
Keywords: Band gap, Co-precipitation, Magnetite nanoparticles, Optical properties
