摘 要:作為未來平板顯示最有力競爭者的有機(jī)電致發(fā)光技術(shù)由于各方面的優(yōu)異表現(xiàn)而引起人們的廣泛興趣，成為當(dāng)今顯示領(lǐng)域的研究熱點(diǎn)。目前有機(jī)發(fā)光的研究主要集中于如何提高的器件量子效率，獲得長久壽命以及高的發(fā)光亮度方面。為了提高器件熒光量子效率，本論文圍繞聚合物摻雜有機(jī)發(fā)光薄膜的材料合成、器件結(jié)構(gòu)設(shè)計與制備等過程，開展了聚合物摻雜熒光發(fā)光機(jī)理的研究。特別是對染料小分子苝酸四甲酯perylene-3,4,9,10-tetracarboxylicacid (TMEP)摻雜薄膜和新型聚合物材料PKMTb的發(fā)光特性與器件結(jié)構(gòu)進(jìn)行了較為系統(tǒng)的研究。論文研究了在發(fā)光聚合物poly(N-vinyl-carbazole)(PVK)中摻雜小分子苝酸四甲酯的各種發(fā)光特性。利用PVK與TMEP不同的熒光特征光譜來研究TMEP摻雜對PVK發(fā)光的影響，以及發(fā)光過程的能量轉(zhuǎn)換關(guān)系。

The research on the new perylene,PVK’s energy transfer and Electroluminescence properties
Abstract: During the past several years, organic electroluminescent (EL) devices based either on small molecules or on polymers are of great current interest due to their potential application in full color display panel covering variety of emission color from blue to red. The study about OLED mainly concentrates on how to increase luminescent efficiency, how to improve device life time and how to get higher luminosity. To improve the luminescent efficiency, this paper focused on doped polymer EL devices involving materials synthetic, device design and preparation. We have carried out systemic research on perylene-3,4,9,10-tetracarboxylicacid(TMEP) doped polymer devices and PKMTb series polymer devices. We have studied the optical properties of TMEP doped PVK films. Using EL and PL spectra, we figured out the influence of introducing TMEP to PVK and the energy transfer process.
