  • Abstract In this study, distributed Bragg reflectors (DBRs) on flexible substrates based on dense ITO and porous ITO bilayers were demonstrated. In the fabrication of the DBRs, the high refractive index ITO films were grown at room temperature by long-throw reactive ratio-frequency magnetron sputtering. On the other hand, the low refractive index porous ITO films were obtained by applying supercritical CO2 treatment at different temperatures and pressures on the spin-coated sol-gel ITO films. The refractive indices of the dense ITO films and porous ITO films were 2.12 and 1.54, respectively. On glass substrates, the DBR with 6.5 period ITO bilayers, the optical reflectance of 95 % was achieved. The stop band and the average resistivity is 110 nm and 2.54×10-3 Ω-cm, respectively. On PET substrates, the DBR with 4.5 period ITO bilayers, exhibits the optical reflectance of 85 % . The stop band and the average resistivity is 126 nm and 2.76×10-3 Ω-cm, respectively.
