本論文的研究主要是利用分子數磊晶機台成長以硒化鋅藍色發光二極體結構激發硒化鋅基板使其混色變成白光.我們在基板的底層鍍上金屬的反射層增加發光的強度.另外我們將P side down 以改變色度座標.因為在一般的結構是N型的基板在下方發光二及提的磊晶層反射回來的光激發基板的590~605mm而產生白光.但光會因吸收而流失如果把 P side down 光可減少一次反射減低吸光的效應.本論文將兩種形式的發光二極體做一比較.

　　另外我們也嘗試用螢光粉來改變色度座標這種不需改變磊晶結構方法可輕易將ZnSe LED由冷色系的白光轉變至暖色系的電球顏色.其色不座標可從X 從 0.3 至 0.45, Y 從0.28至0.4.

　In this thesis, We study ZnSe white Light Emitter Diode. We focus two topics. One is self-emitting white LED. Another one is phosphors effective with ZnSe LED.

　The self-emitting ZnSe white LED we study two types model. One is normal type p-side up. Another is N-side up. The same wafer Used different process we can get more light efficiency and change CIE .

　The ZnSe white LED used phosphors can easily change CIE . The CIE X from 0.3 to 0.45, Y from 0.28 to 0.4, the ZnSe LED color can be change from bluish to golden.
