在本研究中，我們使用新型紅色客發光體材料9-cyano-10-(2-benzothiazoly1)-1,1,7,7-tetramethyl-2,3,6,7-tetrahydro- 1H,5H,11H- benzo[l]pyrano[6,7,8-ij]quinolizin-11-one(RC545T)，此材料是將綠光摻雜客體10-(2-benzothiazoly1)-1,1,7,7-tetramethyl-2,3,6,7-tetrahydro- 1H,5H,11H- benzo[l] pyrano[6,7,8-ij]quinolizin-11-one (C545T)經由化學合成方式，得到新型紅光摻雜客體RC545T，然後以共蒸鍍方式摻雜在發光層中。
本研究分為兩部分:第一部分使用主發光體材料aluminum tris(8-hydroxyquinoline)(Alq3)藉由摻混不同濃度比例客發光體RC545T，找尋最佳摻雜比例，元件結構ITO(1300Å)/NPB(650Å)/Alq3:x%RC545T(300Å)/Alq3(300Å)/LiF(8Å)/Al(2500Å)，在RC545T的摻雜濃度為2%時，可得到較好發光效率。
第二部分則是將不同濃度5,6,11,12-Tetraphenylnaphthacene(rubrene)以及RC545T共摻雜於主發光體材Alq3，主要是要利用rubrene摻雜物，協助將主發光體Alq3有效率地將能量轉移到紅光摻雜RC545T上，我們可得到在電流密度20mA/cm2的發光效率為0.54cd/A，光譜在632nm有最高的發光強度，CIE座標(0.642, 0.347)為飽和度高的紅光元件。我們改善色純度顯示出RC545T是一個很好的紅光摻雜材料應用在OLED上。

In this research, we used the novel material 9-cyano-10-(2-benzothiazoly1)-1,1,7,7-tetramethyl-2,3,6,7-tetrahydro- 1H,5H,11H- benzo[l]pyrano[6,7,8-ij]quinolizin-11-one(RC545T) as a red dopant, which
was synthesized from the green dopant material 10-(2-benzothiazoly1)-1,1,7,7-tetramethyl-2,3,6,7-tetrahydro- 1H,5H,11H- benzo[l] pyrano[6,7,8-ij]quinolizin-11-one(C545T).
First, we used aluminum tris(8-hydroxyquinoline)(Alq3) as a hostmaterial and doped with different concentration of RC545T, with
the configuration of ITO(1300Å)/NPB(650Å)/Alq3:x%RC545T(300Å)/Alq3(300Å)/LiF(8Å)/Al(2500Å). We obtained the maximum efficiency at 2% of RC545T.
Second, 5,6,11,12-Tetraphenylnaphthacene (rubrene) and RC545T as a co-dopant material were doped into the Alq3 layer. The energy transfer from Alq3 to RC545T was mainly assisted by Rubrene. Therefore, we obtained the luminance yield of 0.54 cd/A under the current density of 20mA/cm2, and the peak emission wavelength at 632nm with a CIExy color coordinate of (0.642,0.347).The improved color purity render RC545T a good red-emitting dopant in OLED application.
