摘要：
Bragg mirrors (BM) based on TiOx and SiO2 layers were built on glass and PET substrates at operating wavelength in the visible region. The layers were processed by the sol-gel method at room temperature and dried in air for one hour at 100 degrees C (glass) and 70 degrees C (PET). At these deposition conditions, the refractive indices of the TiOx and SiO2 layers were 2 and 1.49, respectively. The BM were assembled in a multilayer stack of quarter-wave thickness of alternately high and low refractive index materials. We report the experimental and simulated optical reflection spectra of TiOx-SiO2 BM for different number of layers pairs. (C) 2015 Elsevier B.V. All rights reserved.
