Synthesis and characterization of multi-functional ZnO nano ceramic phosphor

This manuscript reports on the synthesis and characterization of a multi-functional ZnO core-shell structure with CoFe2O4 as magnetic materials. To form a combination between optical (ZnO) and magnetic (CoFe2O4) materials, the surfaces of both materials were modified by amine and silica. First, ZnO raw mertials were coated silica using sol-gel methods and -OH group of their surface were modified using amines. Hydrophobic CoFe2O4 nanoparticle was coated with silica and was found to have hydrophilic properties. CoFe2O4 attached silica-coated ZnO core-shell structures were prepared by self-assembly technique and have blue luminescence and magnetic properties.
