本論文研究摻雜BtpIr磷光激發子的PFO共軛高分子薄膜在光激發時的能量傳輸。實驗中比較不同摻雜濃度的高分子薄膜的光激發光( Photo luminance )光譜以及光注入激發吸收( photo-induced absorption PA )來觀察PFO的單重態激子以及三重態激子在(Btp)2Ir摻雜後的改變。由摻雜之後單重態激子被淬熄以及三重態激子的生命期縮短,發現Forster能量傳輸以及Dexter能量傳輸均有發生。然而隨摻雜濃度的增加(Btp)2Ir並無法完全淬熄PFO中的激子,這可能是由於(Btp)2Ir無法均勻分布於PFO薄膜所導致。
This thesis studies on energy transfer process in conjugated polymer PFO doped with phosphorescent emitter (Btp)2Ir. By comparing photo-luminance (PL) spectrum and photo-induced absorption (PA) signal of polymer films with various doping concentration, we investigate the change in the population ratios and life time of singlet and triplet exciton of PFO. From the quenching of singlet exciton of PFO and reduced life time of triplet exciton of PFO, it concluded that both Forster energy transfer and Dexter energy transfer happen. However, high doping concentration cannot quench exciton of PFO completely and it may be due to the fact that (Btp)2Ir cannot disperse uniformly in PFO film.
