碩士 === 逢甲大學 === 電子工程所 === 96 === In this study, we tried to use iron chloride and NaH2PO4 hydrazine to synthesize α-Fe2O3 nanoparticles Successfully. The obtained core particles were coated with uniform layers of silica by hydrolysis of TEOS. In the other case, we tried to use cobalt chloride, nickel chioride, sodium Hydroxide, PVP and hydrazine to synthesize cobalt and nickel nanoparticles Successfully. Then, we tried to combine by cobalt and nickel nanoparticles with Sulphur in glass at high temperature. Then, we analyzed the nanoparticles surface shape and particle size by the TEM and FESEM, the structure by the X-ray diffraction (XRD) and UV-Visible-NIR spectrometer and measure the magnetic properties by the vibrating sample magnetometer (VSM).
