Abstract
Perovskite phase Ba0.6Sr0.4TiO3 thin film has been prepared using sol-gel technique. IR transmittance spectrum shows that the bands are located in the range of 1100 and 400 cm(-1). These bands could be due to Ba-O-Ti, Sr-O-Ti or TiO3 bonds. The response of Ba0.6Sr0.4TiO3 film to IR radiation has been investigated using capacitance-voltage (C-V) and current density-voltage (J-V) characteristics, the results show the capacitance slightly increase as the frequency of the IR radiation decreases, however, no appreciable change on the leakage current curve is observed.
