Thin films of Barium Zirconium Titanate (BaZrxTi1-xO3) with various composition, namely x = 0,55; 0,60 and 0,65 have been successfully prepared using the sol-gel method. The films were annealed at 600 ° C and 650 ° C for 1 hour. The thin films were characterized using UV-Vis spectroscopy and X-Ray Diffractometer (XRD). UV-Vis spectroscopy provides absorbance data, that can be used to obtain t…
