Photoflex project : photochromism with silver np
Ag SiOCH HEF R&D Rewritable films based on TiO2/Ag materials deposited on flexible supports for colored photo-inscriptions Sol gel Spin coating Ink jet Magnetron sputtering Alternative sputtering of TiO2 and Ag Laser photo-inscription Writting Erase We investigate the effects of reduction processes on the formation of silver nanoparticles in mesoporous titania films. The later are impregnated with silver salt and then either exposed to UV laser light, chemically treated or annealed. Depending on the reduction process, the NP are confined inside the mesopores or not, leading to different NP size distributions and to various film colors. These TiO2/Ag nanocomposite films also exhibit different photochromic behaviours when exposed to visible laser radiations. We characterize and interpret the color changes as well as the NP deformation and oxidation under visible illuminations. Date : 4/21/2017 Electromagnetic model developed Granted by
