摘要: | 固態白光電化學元件其簡易的結構、溶液式製程、低功耗及可使用低活性金屬,在未來會比其它有機發光元件更具潛力,不論是在照明或是各種顯示技術方面等等。本文發表新型白光離子性高分子材料,兼具藍光與黃光基團,所以單一材料就可發白光,可以避免不同光色的材料混合時,因極性的不同發生相分離現象。 此高分子的成膜性佳,經旋轉塗佈後膜層均勻,每個元件所表現出來的特性相當一致,在低電壓3 伏特下創造了目前高分子白光電化學元件最高的功率效率1.56 流明/瓦,外部量子效率0.3 %,在光色部分色座標非常接近CIE'1931 (0.33, 0.33)、演色性指數大於85,以上實驗結果說明本文材料具有高度應用潛力。 A series of polyfluorene (PF) electrolytes bearing BF4-, or PF6- counterions were used in light-emitting electrochemical cells (LECs). 2,1,3-Benzoselenadiazole moieties were incorporated into polymer main chains to produce single-component white light-emitting polymers. The optimized spin-coated LECs showed a maximum power efficiency of 1.56 lm/W at a low operation bias of 3 V. The single-component LEC device exhibited pure white light emission with CIE'1931 coordinates approaching (0.33, 0.33) and high color rendering index (CRI) >85, referring to its potential use in solid-state-lighting application. |
