纳米金属光栅上的表面等离子体共振(SPR)对临近材料折射率变化敏感,因此通过改变临近材料折射率,可以实现纳米金属光栅透射光谱的颜色调制进而用于显示器件,该调制器具有结构简单、色度和对比度高等特点。通过仿真设计实现了红绿蓝三个子像素的透射彩色显示。实验制备了周期为520 nm、铝厚度为50 nm的双层金属光栅,并通过改变光栅临近材料折射率,实现了空气中为绿色亮态显示、蔗糖溶液中为暗态显示的效果,明暗对比度达到122。从理论和实验两方面证明了基于金属光栅结构的彩色显示和亮度调节的可行性,为未来电浸润显示器件提供了新的设计方案。 Surface Plasmon Resonance (SPR) on nanometallic gratings is sensitive to the refractive index changes of the adjacent materials. Therefore, by changing the refractive index of the adjacent materials, the color modulation of the transmission spectrum of the nanometallic gratings can be realized for the display device. The modulator has the advantages of simple structure, , Chroma and contrast characteristics. Transmitted color display of three sub-pixels of red, green and blue is realized through simulation design. A double-layer metal grating with a period of 520 nm and an aluminum thickness of 50 nm was fabricated experimentally. By changing the refractive index of the material adjacent to the grating, a green bright state in air, a dark state in sucrose solution, Reaches 122. The feasibility of color display and brightness adjustment based on the metal grating structure is proved both theoretically and experimentally, and a new design scheme for the future electro-immersion display device is provided.
