실리콘 나노구조와 박막 공진층의 혼합구조를 이용한 반사형 컬러필터의 색범위 확장

Abstract

The nanophotonic structural color is currently a promising research field due to outstanding optical properties. Here, we demonstrate tuning colors with silicon nanowires by stacking on reflective color filters. The colors can be tuned depending on geometrical parameters (i.e. diameter, periodicity of silicon nanowires). Stacking these layer facilitates the linear combination of two different reflectance spectra, thereby enabling widening of the gamut in color technology.
