摘要: In the present study, a facile one-pot synthetic route, utilizing strong polar organic solvent, N-methyl 2-pyrrolidone (NMP), is demonstrated to obtain highly monodispersed ferrite nanocrystals. The equimolar mixture of oleic acid, C17H33COOH (R-COOH), and oleylamine, C18H35NH2 (R′-NH2), was used coat magnetic Structural properties nanocrystals were studied by multitechnique approach including X-ray diffraction (XRD), high resolution transmission electron microscopy (HRTEM), Fourier transform infrared (FTIR) spectroscopy, thermogravimetric analysis (TGA), photoelectron spectroscopy (XPS), vibrating sample magnetometry (VSM), Mossbauer spectroscopy. FTIR spectral indicates oleylamine helps in deprotonation resulting formation an acid–base complex, R-COO¯:NH3+-R′, which acts as binary capping agent. coordination differences iron XPS analysis. ...
