Film Strontium Titanate (SrTiO3) doping Cupric (Cu) with various concentrations (0%, 0.5%, 1%) was successfully synthesized using the Chemical Solution Deposition (CSD) method. The films were deposited above Si type-p (1 0 0) substrate in five layers using a spin coating technique (3000 rpm, for 60 s) with a concentration of 2M. The annealing process was held at 850 oC for 8 hours with a temperature increase rate of 1.67 oC/min for crystallization, then optical properties were characterized using spectrophotometric methods. The result of FTIR with the Kramers-Kroning quantitative method obtained a decrease in the wavenumber of phonon vibration mode Transverse Optic (TO), Longitudinal Optic (LO), and the intersection of the real and imaginary dielectric which showed a red shift with the addition of Cu concentration. The optical properties of SrTiO3 thin films by doped Cu indicate the potential for the applications of visible light photoconduction such as light sensors.
