Abstract:


Background: Iron oxide (γ-Fe2O3) nanoparticles have been prepared by a simplified coprecipitation method.

Methods: X-ray diffraction peaks of the prepared nanoparticles match well with the characteristic peaks of crystalline g-Fe2O3 as per JCPDS data (JCPDS Card No. 39-1346) and absorption peak at 369 nm along with band gap 2.10 eV suggesting the formation of (γ-Fe2O3) nanoparticles.

Results: The γ-Fe2O3 nanoparticles are spherical in nature with a diameter around ~10 nm.

Conclusion: The crystalline g-Fe2O3 nanoparticles exhibit excellent super-paramagnetic behavior not only at room temperature (300K) but also at a temperature as low as 100K.

Keywords:

Iron oxide nanoparticles, co-precipitation, UV-vis absorption, X-ray diffraction, super-paramagnetic, drug delivery.
