Sintesis dan Karakterisasi Magnetik Kuantum Dot Fe3O4 Dengan Metode Kopresipitasi

Abstract

The unique properties of the magnetic quantum dot Fe₃O₄ make it widely synthesized by different methods and applied in the biomedical field. The synthesis method plays an important role in determining the optical properties of the magnetic quantum dot Fe₃O₄. This study aims to determine the magnetic synthesis of quantum dot Fe₃O₄ coated with oleic acid by coprecipitation method. Quantum dot Fe₃O₄ magnetic synthesis method by coprecipitation using oleic acid for functionalization of Fe₃O₄ quantum dot magnetic. The results of the FTIR analysis showed five main absorption bands namely O-H, C-H, C=C, C-O, and Fe-O which indicated that the magnetic quantum dot Fe₃O₄ was successfully functionalized with oleic acid.
