Abstract: Monodisperse wurtzite ZnO nanorods with the length of 4 μm and the diameter of 200 nm were prepared via a simple solution chemical process. The crystal phases and the microstructure of nanorods were studied via XRD, SEM, respectively. The properties of the excitonic luminescence are investigated by using the laser power dependence and temperature dependence of photoluminescence (PL) spectra.

Abstract: Fe3O4 nanoparticles were simply prepared by a wet chemical solution method. In this method, poly (N-vinyl-2-pyrrolidone) (PVP) was used as surface modified reagent to control the shape of the product. Transmission electron microscopy (TEM), high-resolution transmission electron microscopy (HRTEM), and X-ray diffraction (XRD) were used to characterize the asprepared Fe3O4 nanoparticles. Furthermore, the magnetic properties of the sample were investigated by a VSM (vibrating sample magnetometer) technique.
