摘要(中)

本論文研究致力於建立一套 YAG 螢光粉摻雜 ZrO2 散射粒子之光學模型，依循孫慶成博士團隊所建立之螢光粉模型之流程，加入散射粒子後並在模型中引進等效折射率以及等效粒徑之概念，利用實驗模擬計算得到螢光粉摻雜散射粒子之重要特性參數。其中包含等效散射模型建立、等效吸收係數與等效轉換係數之模擬計算，並以實際封裝與模擬進行頻譜、色座標與封裝效率等驗證。最後，利用此模型進一步探討 YAG 螢光粉摻雜 ZrO2 散射粒子對封裝效率、螢光粉減量與色彩空間均勻性之影響，及 ZrO2 摻雜後之物理影響與解釋。

摘要(英)

In this thesis, we have developed an optical model of YAG phosphor with mixing ZrO2 scattering particles. The process of optical modeling is based on the traditional phosphor optical modeling procedure established by Dr. Sun’s group. By following the process, we obtain a set of effective parameters, such as the effective scattering model, effective absorption coefficient, and conversion efficiency in both experiment and simulation. In the verification, the chromatic performances and packaging efficiency of the real LEDs are measured and compared with the modeling simulation. Then we use the new optical model to study of packaging efficiency, phosphor reduction and angular correlated-color-temperature deviation with YAG phosphor adding ZrO2 scattering particles. The properties of adding ZrO2 is summarized in the final.
