Abstract
In this research, the optical properties of nickel ferrite nanoparticles were studied. Samples were prepared by bombarding nickel ferrite alloy with a nema 23 laser with a pulse number of 100 pulses and an energy of 250 millijoules with ethylene liquid. The samples were bombarded for 150-200 pulses and the effect of irradiation on the absorbance, transmittance, reflectivity and absorption coefficient was studied. It was noted that the more the number of pulses increased, the more absorbance increased due to the decrease in the grain size. Also, a decrease in transmittance was noted with an increase in the number of pulses because the relationship between transmittance and absorbance and an increase in reflectivity is that metals increase the reflection of the incident rays on the sample as they provide free electrons that cause an increase in reflectivity and the absorption coefficient increases with an increase in absorbance.
