摘要：

均匀的硫化镉（CdS）微球具有较高的折射率,由其组成的光子晶体颜色亮丽,具有低角度依存性,近年来在结构生色领域被广泛应用。但是,目前较为成熟的合成均匀硫化镉微球的方法存在有机溶剂的大量使用和高温能耗大等问题。因此,设计了一种在水溶液中合成均匀硫化镉微球的绿色合成方法,通过受控注射的方式辅助进料,解决了金属盐前驱体在水中水解速度过快导致微球生长不平衡的问题。同时,受控注射的方式可以更有利于控制体系中二价镉的浓度,成功地合成出180~410 nm的均匀硫化镉微球。进一步通过水平诱导组装的方式构筑了以不同粒径的硫化镉微球为基元的三维光子晶体结构。这种光子晶体薄膜展示出亮丽、低角度依存的结构色,更利于结构色在颜色显示等领域的应用。

Abstract:

Uniform cadmium sulfide（CdS） microspheres have high refractive index,and the photonic crystals composed of them have bright color and low angle dependence,which have been widely used in the field of structural color in recent years.However,the current mature methods for the preparation of uniform CdS microspheres have some problems,such as the large use of organic solvents and high energy consumption at high temperature.Therefore,a green preparation method for preparing uniform CdS microspheres in aqueous solution was designed.The controlled injection assisted feeding solved the problem of unbalanced growth of microspheres caused by too fast hydrolysis of metal salt precursors in water.At the same time,the controlled injection method could be more conducive to controlling the concentration of Cd²⁺ in the system and successfully synthesized uniform CdS microspheres with 180~410 nm.Further,three-dimensional photonic crystal structures based on CdS microspheres with different particle sizes were constructed by horizontal induced assembly.This photonic crystal film showed bright and low angle dependent structural color,which was more conducive to the application of structural color in color display and other fields.

Key words: CdS microspheres, synthesis in aqueous solution, bright structural color, low-angle dependence
