摘要: 固態有機白光電化學元件由於具有結構簡單、可溶液製程、可使用非活性金屬電極與低功耗等優點,在白光照明的應用或顯示技術方面極具潛力。本文使用會發藍光的聚芴高分子結合紅光錯和物來發出白光,因此高分子發光材料已具離子性,故不須再摻雜離子性鹽類與減緩相分離的離子傳導材料,加上此材料為單一白光材料,也不須透過主客體之方式與改變元件結構來調整光色,因此大幅縮短製程步驟。 本實驗成功使用此材料做出白光電化學元件,在低操作電壓3.2 V、3.3 V即可發出白光,光色部分其色座標接近純白座標(0.33,0.33),演色性指數96,以上說明本材料在白光照明上有極高的應用潛力。
In this work, ionic polyfluorenes were utilized in active layers of white light-emitting electrochemical cells (WLECs) .Red-emitting iridium complexes were incorporated into polymer main chains to produce single-component white light-emitting polymers. By using ionic polyfluorenes, white-light LECs showed advantages of low operation voltage, without adding additional salts or poly(ethylene oxide)(PEO) .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) >95, referring to its potential use in solid-state-lighting application.
