Selective scattering of blue and red light based on silver and gold nanocubes
Abstract
Selective scattering of red-, green- and blue-light and transmitting other visible light to achieve transparent projection screen has been proposed recently based on metallic nanoparticle's localized surface plasmon resonance (LSPR). However, dielectric (TiO2) substrate/silver (Ag) nanocube structure was only demonstrated to selectively scatter blue-light in the backward direction. Given human eyes are sensitive to green-light, it is of interest to find out how to achieve selective forward-scattering of blue- and red-light and selective backward-scattering of red-light. In this work, through numerical simulation, forward and backward scattering properties of dielectric substrate/Ag (or gold) nanocube structures are investigated. And based on these properties, three designs are proposed which can achieve selective scattering of blue- and red-light in forward or backward or both directions.
