Comparative study of transparent display using aperiodic arrays of Si–SiO2 core–shell nanoparticles

Abstract

In this paper, the different arrays of core–shell nanoparticles are investigated to propose a high-quality transparent display. In this work, we compare the optical properties of the different types of deterministic aperiodic arrays in a visible range. To realize this idea, the Si–SiO2 core–shell nanoparticle is used, and with varying radius and distance between nanoparticles, the transparency and contrast of the proposed transparent monitor are investigated. By comparing the deterministic aperiodic and periodic arrays, we show that the Fibonacci structure can achieve a higher scattering rate as well as narrow bandwidth. We use the array of nanoparticles based on the Fibonacci configuration by an appropriate lattice constant to obtain a very sharp scattering profile. We use the Finite-Difference Time-Domain numerical method to simulate and calculate the optical properties of the deterministic aperiodic and periodic arrays of nanoparticles. Finally, we demonstrate the effect of several nanoparticles on the bandwidth, peak of scattering, and absorption cross-section.
