Structure, thermal, magnetic and magneto-optical properties of core/shell Fe3O4@MoS2 doped diamagnetic glasses

摘要

Glass containing nanoparticles is attractive for plasmonics and photonics applications due to the significant optical and band gap merits. In this paper, 30/70 rim Fe3O4@MoS2 core/shell nanocomposites were synthesized with a specific surface area of 70.1050 m(2)/g. XRD spectra revealed the good crystallization peaks of Fe3O4 and MoS2 at 14.4 degrees, 30.1 degrees, 32 degrees, 35.9 degrees, 43.1 degrees, 50.8 degrees, 57.2, and 62.58 degrees, respectively, and the increases of lattice parameter of Fe3O4 and MoS2 confirmed that there was the reaction between them. The vibrations of Fe-O bonds (616 cm(-1)), Mo-S bonds (similar to 600 cm(-1)) along with A(1g) of Fe3O4 and characteristic E-2g(1) and A(1g) of MoS2 were displayed in their FT-IR and Raman spectra, respectively, indicating the good core/shell nanostructure of Fe3O4@MoS2.
