本論文首先針對現今高效率之藍光OLED元件提供色純度之改善方案，透過搭配具分佈式布拉格反射鏡之陽極基板再加上OLED元件有機層之厚度微調優化後，成功改善藍光OLED色純度不足之問題，將藍光元件之CIE座標由(0.14,0.35)改善至(0.14,0.14)。
第二部分研究兩款具有凝集誘導發光(Aggregation induced emission, AIE)特性之材料：TPATPE及2TPATPE，由於其具有立體性結構，此類材料可以利用作為良好的有機電激發光元件，能以簡單的製程方式展現傑出的效率。首先透過架設光學量測系統量測此兩款材料之自發輻射放大(Amplified Spontaneous Emission, ASE) 特性，萃取其閥值、增益、損耗等係數，判斷此兩種材料皆具有良好的ASE閥值分別為2.7kW/cm2和4.9 kW/cm2以及高增益係數19cm-1與22cm-1，此結果證明兩材料皆具有優異的光放大特性，非常適合做為有機雷射元件之介質。接著我們也進一步對兩款材料製作二階的光激發式分佈回饋雷射元件，透過具有週期性光柵結構的基板使其產生共振腔效應而達到光譜窄化及光強度放大之作用，最後利用此兩款材料製作雙層式螢光有機電激發光元件，透過簡易的製程能展現出優異的亮度及效率表現，TPATPE與2TPATPE之OLED元件EQE最大值分別為4.3 %及4.6%，這樣的結果對於固態照明或式顯示器的應用上皆是相當有利的。

The first part of this thesis is concentrated on the color purity performance improvement of blue phosphorescent OLEDs. We integrated a high efficiency blue OLEDs with conducting DBR anodes, then optimized this device by modulating the thickness of organic films. With this configuration, we successfully improved the color purity of the blue-emitting device. The CIE 1931 color coordinate of the blue-emitting device with cavity structure was located at (x,y)= (0.14,0.14), and it of the device with no cavity structure was located at (x,y)=(0.14,0.35).
In the second part of this thesis, we investigated two materials with aggregation induced emission (AIE) properties named as TPATPE and 2TPATPE. Due to their high steric hindrance, they can be well utilized in high efficiency OLEDs. First, we set the amplified spontaneous emission (ASE) experiments to measure their ASE thresholds, ASE spectrum, gain coefficients and loss coefficients. The results revealed that both TPATPE and 2TPATPE have good optical amplification properties with ASE thresholds about 2.7kW/cm2 and 4.9kW/cm2 and gain coefficients are 19cm -1 and 23cm-1, respectively. With a suitable resonant condition realized by 1-D DFB structure and the high gain materials, spectral narrowing and optical amplification properties were observed. Finally, two double-layered florescent OLEDs with high efficiencies were demonstrated. The EQE of TPATPE and 2TPATPE devices were 4.3% and 4.6%, respectively. This results indicated that both of these two materials are well suitable for display or lighting applications.
