The present paper demonstrates synthesis, characterization and electrical properties of relaxor ferroelectric Eu(CH3COCHCOCH3)(3)center dot XH2O doped Lead Magnesium Niobate nano scale powders and PMN thin films on n-type Si substrates using sol-gel technique for capacitor applications. With this respect, transparent solutions were prepared from Pb, Mg and Nb based precursors, methyl alcohol and glacial acetic acid (GAA). After the sintering, the PMN powders were milled for 12 hours at room temperature to obtain PMN based nano scale powders. Finally, the powders were dispersed in alcohol and the obtained suspensions were deposited on n-type Si substrates using drop and spin coating systems and then annealed at 730 degrees C for 1 hour in air. Thermal, structural, microstructural, optical and mechanical properties of the powder and the coatings were characterized through X-ray diffraction (XRD), scanning electron microscopy-energy dispersive spectroscopy (SEM-EDS), atomic force microscopy (AFM), Shimadzu Dynamic Ultra Micro Hardness Testing (DUH), Scratch Tester.
