| Popis: | Noble metal plasmonic resonance has been utilized in optical data storage widely for its excellent photo-transformation efficiency. TiO2 nanoporous films deposited with Ag nanoparticles present outstanding polarization-response and color-modulation ability. However, the low exposure-sensitivity at single wavelength inhibits their application in optical information processing, which is urgent to be improved by innovative methods. Here, we report that Ag nanoparticles were deposited efficiently via continuous laser irradiation in the TiO2 nanoporous film treated by tannic acid, presenting high-efficient monochromic absorption property. As a result, two sets of holograms were recorded sequentially at the same point of the film with orthogonal circular polarization configurations. The colored reconstruction of the mixed holograms was achieved by utilizing laser polarization state as chrominance segmentation channel. Our method provides a distinctive route for enhancing the photo-energy conversion efficiency of plasmonic nanoparticles, and paves a way to develop advanced display device. |
