摘要

Fe_3O_4 nanoparticles were synthesized and doped into two glass systems (Na_2O-B_2O_3 glass and PbO-Bi_2O_3-B_2O_3-GeO_2 glasses) at low concentrations using traditional glass melting method. The formation of Fe_3O_4 nanoparticles was obtained through coprecipitation of Fe(II) and Fe(III) in alkaline media. The size of the Fe_3O_4 nanoparticles was observed to be around 15 nm. The structure and properties of doped glasses were studied by X-ray diffraction (XRD), scanning electric microscope (SEM), UV-VIS spectray, FT-IR spectray analysis and Faraday rotation test. Compared to the host glass, Fe_3O_4 nanoparticles doped glasses shown enhanced Faraday effect in term of Verdet constant and will have potential application in magneto-optical devices.
