The material was characterized using a transmission electron microscope (TEM), Fourier transform infrared (FT-IR) spectroscopy, thermogravimetric analysis (TGA), and optical absorption spectroscopy.  Electrical and dielectric properties were performed by impedance spectroscopy at frequencies (20 Hz-1 MHz) in the temperature range (303-473 K).
