摘要: 我們提出一個三年期之台日合作研究計畫「有機與高分子光電材料元件之基礎研 究」,其目的在結合雙方互補之技術與資源,對有機與高分子光電材料元件(OLED、OLEFET 及DSSC)的基本過程進行深入的研究與探討。元件電致發光或光電轉換效率的特性與材 料的光譜特性、激發態動態學以及他們的電場效應息息相關,要了解控制效率的關鍵因 素,我們將進行電致吸收(vis. and IR)光譜/放射光譜、光電流電壓特徵曲線、以及其 對應的動力學基礎研究。分析這些元件電場/光電效應或動力學的結果可以幫助我們了 解其運作機制,以及其和元件效能的對應關係而促使我們未來能設計出功能更強大的元 件。其中有機/高分子/奈米材料的合成、OLED 與DSSC 元件的製備、以及相關光譜動力 學的研究將在台灣進行,而OLEFET 元件製備與相關材料的電場效應研究則由日本團隊 負責。吾人預期這個國際合作研究計畫將會有非常豐碩的成果產出。
as efficient organic light emitting diodes (OLEDs) and organic light emitting field effect transistor (OLEFET), and dye-sensitized solar cells (DSSC) using organic molecules, novel polymers, and nanomaterials. 2) In OLEDs, multilayer thin films including electron, hole transporting layers, and emitting layer are deposited between electrodes by spin coating or vapor deposition. OLEFETs which are operated under the action of drain-source bias are also constructed. DSSC is a sandwich-type device containing dye sensitizers, electron and hole transporting layers. The electroluminescence or conversion efficiency of these devices depends strongly on the spectral property, excited-state dynamics and their electric field effects. To understand the critical factors governing the efficiency, UV-Vis electro-absorption and electro-photoluminescence spectra, photocurrent and photovoltage, and their decay profiles, IR electro-absorption and transient absorption spectra will be recorded. 3) Analysis of these electric and photo-electric effects will lead to better understanding of the emission mechanism and efficiency of these nano devices and provide guidelines for making nano devices with improved performance. 4) Polymers, organic sensitizers and nanomaterials will be synthesized and nanodevices of OLED, DSSC, and OLEFETs will be fabricated in Taiwan and Japan, respectively. The electric-field effect in the UV-Vis spectral region will be carried out in Japan, and those in the IR region will be performed in Taiwan. 5) Understanding of the detailed mechanism is expected to lead to development of efficient and durable light-emitting and photovoltaic devices that can be used in many applications, including flexible display, solar cell or optical sensor.
