摘　　要：在自然界和日常生活中,由入射光与结构之间的干涉而产生的结构色是普遍存在的。与传统的化学颜料和染料相比,结构色具有损耗低、环保、耐久性高等优点,在显示、光存储、传感和信息加密等领域具有广阔的应用前景。近年来,随着微纳加工技术和表征手段的不断发展,利用人工制造的金属微纳结构来产生结构色成为一种主要的方法。但是表面等离激元结构色不可避免地会产生高的损耗,这使得散射截面变小,从而导致了色度范围受限、颜色饱和度降低、明度降低等一系列问题。与等离激元结构相比,谐振介质结构和混合结构具有损耗低、场约束强、散射截面大等优点。因此,介质结构色的研究对实现超高分辨率的鲜艳结构色具有重要意义。本文从介质结构色的理论基础出发,按照介质材料的种类(硅、二氧化钛、氮化硅、二氧化硅和其他材料),对其最近的研究进展进行了综述,提出了介质结构色这一快速发展领域未来可能的发展方向和存在的挑战。Structural colors resulting from the interference between incident light and structures are ubiquitous in nature and daily life.In contrast to conventional chemical pigments and dyes,structural colors have the advantages of low loss,environmental protection and high durability,and have broad application prospects in the fields of display,optical storage,sensing and information encryption.In recent years,with the continuous development of micro-nano processing technology and characterization methods,the use of artificially manufactured metallic nanostructures has become the main method to produce structural colors.However,inevitable high loss of resonant plasmonic structural colors will lead to reduced scattering cross-sections,so it causes a series of problems like limited hue range,reduced color saturation and low value.Compared with the plasmonic structure,resonant dielectric and hybrid structures are subjected to low loss while providing strong field confinement and large scattering cross sections.Therefore,the research of dielectric structural color is of great significance to achieve bright structural colors in ultra-high resolution.In this paper,we first introduce some theoretical foundations of dielectric structure colors,and then review the latest research progress according to the types of dielectric:silicon,silicon dioxide,titanium dioxide,silicon nitride and other materials.Finally,we put forward our own opi-nion on the possible future development direction and existing challenges of the rapid developing field of the dielectric structure colors.
