Transparent Display by the Scattering Effect of Plasmonic Au-Ag Nanoparticles

A transparent display allows us to see both the projection image displayed on it and the view behind it at the same time, which can be widely used in the car windshield, shop windows, and so on. To achieve the transparent display with the simple and easily available plasmonic nanoparticles, plasmonic Au-Ag nanoparticles with the strong scattering ability were used to achieve the objective of selectively scattering red, blue, and green light for the transparent screen in this work. Firstly, the optimized size parameters for these three color transparent displays were obtained theoretically. On the other hand, plasmonic nanoparticles used for the blue and green color transparence screen were reported in the previous experiments. Finally, a red color transparent display with the wide viewing angle was made based on the optimized Au nanoparticles experimentally.
