摘　　要：基于高色纯度的光源的显示技术具备宽色域、高色彩饱和度和高对比度的特点,能够给人们带来更好的视觉体验。近年来窄带宽光源的研制受到越来越多学者的关注。本文选择了三种典型的发光聚合物构筑聚合物发光电化学池(PLEC),利用分布式布拉格反射镜(DBR)和铝薄膜为腔对出射光谱进行窄化。结果表明,红绿蓝三色聚合物发光电化学池出射光的带宽可缩短至10、11和8 nm,色纯度得到了极大的提升。这种高色纯度光源的获得有望显著推动下一代显示技术的发展。The display technology based on high color purity light sources has the characteristics of wide achievable color gamut,good color saturation and high contrast ratio,which can bring people better visual experience.In recent years,the development of narrow bandwidth light sources is receiving more and more attentions.Here,three typical light-emitting polymers were selected to construct polymer light-emitting electrochemical cells(PLEC),and a distributed Bragg reflector(DBR)and Al thin film were used as cavities to narrow the emission spectra.The results showed that the bandwidth of the emitted light from the red,green and blue PLECs dramatically narrowed down to 10,11 and 8 nm,respectively,and the color purity has been greatly improved.The acquisition of such high color purity light sources is expected to significantly promote the development of next-generation display technology.
