Color Transparent Monitor using Si/SiO2 Core-Shell Nanoparticles: Optimum Color Selection

Abstract

In this paper, core-shell nanoparticles are used to provide a transparent high-quality display. To realize this idea, Si-SiO2 core-shell nanoparticles have been used to achieve the most suitable nanoparticle composition for a transparent color display with high transparency and contrast. For color transparent monitor the superimposed QDs are used. There is a basic question for the realization of the proposed transparent monitor. What is the ratio of nanoparticles (ratio of three QDs) for three colors in the proposed monitor? In this paper, we are going to acknowledge this question. As it is clear, the scattering peaks for red, green, and blue are different because of the physics of the scattering that is wavelength-dependent. Thus, the optimum ratio for each color should be obtained. The numerical method of Finite-Difference Time-Domain is used to simulate and calculate the optical properties of the proposed transparent monitor. The effect of different combinations of nanoparticles to have the maximum dispersion at blue, green, and red wavelengths and the minimum absorption at other wavelengths has been investigated. Finally, the optimum ratio and arrangement of nanoparticles for all colors are reported and numerically evaluated.
