通常基板、電極/有機材料界面處的折射率失配將導致有機發光二極體中近 80% 的光損失。
本論文研製之有無增亮膜對有機發光二極體對亮度的影響，先使用各種不同參數去調製而成增亮膜溶液，觀察不同種類增亮膜的影響。使用分光比色計去比較有無增亮膜對元件的亮度差異，還使用掃描電子顯微鏡和CCD輔助視覺顯微鏡去觀察它的奈米球表面狀況和排列情況。
把製作好的增亮膜放上有機發光二極體的前面，然後要對好有奈米球的地方，對完有奈米球的地方後，在對有機發光二極體施加5V的電壓，並觀察有無增亮膜的亮度變化，它的亮度從165.6 cd/m2變成196.5 cd/m2，代表這個增亮膜是有效的。接者使用掃描電子顯微鏡和CCD輔助視覺顯微鏡，去觀察它的表面結構，對其進行增亮膜的形貌分析，最後使用分光式色度計的光譜色度圖去觀察有無它的電壓電流亮度特性。

The mismatch of refractive index at the interfaces of substrate, electrode/organic material will cause nearly 80% light losses in the organic light-emitting diodes (OLED).
This paper studies the brightness enhancement film (BEF) on the brightness of OLED components, using different weights of parameters. The study starts with preparing the BEF, and observe the influence of the BEF on the brightness, studies the relationship between BEF parameters and brightness and surface condition. Using a spectrocolorimeter (PR650) to compare the difference in the brightness of the diode with or without the BEF. Then, using a scanning electron microscope and Charge-coupled Device(CCD) to observe its nanosphere shape and arrangement.
Put the finished BEF on the front of the OLED, and then align the place with nanospheres. After aligning the place with nanosphere, apply a voltage of 5V to the OLED. And observe whether the brightness of the BEF changes, its brightness from 165.6 cd/m2 to 196.5 cd/m2, which means that the spin-coated BEF is effective. Then use the scanning electron microscope(SEM) and CCD-assisted visual microscope to observe its surface structure, analyze the morphology of the BEF, and finally use the spectrocolorimeter of the sprctrocolorimeter to observe its presence or absence voltage、current characteristics and luminance.
