摘要:	本論文主要以時域有限差分法模擬有機發光二極體的光學頻譜。我們透過校正頻譜修正近場至遠場轉換所造成的模擬誤差，讓時域有限差分法模擬的遠場零度角光譜與即時性多角度光譜所量測的零度角光譜相符，以此証明時域有限差分法確實可模擬有機發光二極體的光學光譜。我們探討不同膜層厚度模擬Alq3元件遠場光譜，解釋在微共振腔中，廣角干涉效應對光譜所造成的影響，並運用時域有限差分法驗證此效應。在廣角干涉效應中，電偶極位置至金屬電極表面的距離(Lrec)為一個非常重要的參數，透過時域有限差分法模擬，我們推測電子電洞復合位置所產生的電偶極，應當為一區域範圍厚度復合。;In this thesis, the finite-difference time-domain method is used to simulate the optical spectrum of organic light-emitting diodes. We correct the simulation error caused by near-field to far-field conversion by correcting spectrum, so that the far-field zero-degree angle spectrum is consistent with the finite-difference time-domain method and one-snap multi-angle spectroscopy optical system(OSAS). This proves that the finite-difference time-domain method can indeed simulate the optical spectrum of organic light-emitting diodes. We demonstrate the far-field spectra of simulated Alq3 components with different film thicknesses, explain the wide-angle interference effects on the weak micro-cavity effect, and verify this effect using the finite-difference time-domain method. In the wide-angle interference effect, the distance from the position of the electric dipole to the surface of the metal electrode(Lrec) is a very important parameter. Through simulation of the finite-difference time-domain method, we speculate that the electric dipole generated by the composite position of the electron and the hole should be in a region range.
