研究做出來的白光 CIE1931 座標位於(0.3339,0.3192),後續再利用改 變工作電流(10-50mA )得到對應之色溫隨電流提升而下降,相反的演

第二部分的實驗為以光聚合製程製作出鈣鈦礦(Perovskite)量子 點有機發光薄膜,以及使用 CdSe/ZnS 與鈣鈦礦(Perovskite)量子點製 備白光 LED,綜合本研究之結果如下:

1. 利用光譜儀來對本實驗製備之白光 LED 進行量測,可以得到目前本 研究做出來的白光 CIE1931 座標位於(0.3216,0.3237),後續再利用改 變工作電流(10-50mA )得到對應之色溫變化不大,但是演色性指數 CRI 的數值則隨電流提升而下降,推測是當工作電流密度增加時,藍 光 LED 發光強度也會跟著增強,促使鈣鈦礦(Perovskite)量子點產生 降解,導致鈣鈦礦(Perovskite)量子點之發光效率下降,使得 CRI 值隨 之下降。接著對合成之白光 LED 作時效性測試可得知,鈣鈦礦 (Perovskite)量子點在白光 LED 中,隨著使用時間的增加會產生降解 的現象,原因是鈣鈦礦(Perovskite)量子點若接受到藍光的照射變會開 鈦礦(Perovskite)量子點的與純高分子的 5%分解溫度分別為 212.2℃

與 287.6℃,純高分子很明顯高出許多,配合 DTG 分析可得知有加入 鈣鈦礦(Perovskite)量子點較純高分子分解速率還要高,所以可得知有 加入鈣鈦礦(Perovskite)量子點會使本研究開發出來的高分子熱性質 表現下降。

第三部分的實驗為探討加入甲基三甲氧基矽烷壓克力單體(6070)對 附著力之影響,將配置好的高分子單體和量子點再分別加入不同重量百 分比之甲基三甲氧基矽烷壓克力單體(6070)之混合物滴滿塑膠基板,以 大小 2 cm 2 cm 來製作試片,經過旋鍍後進行光聚合反應得到一有 機發光薄膜,利用萬能材料試驗機對其做正向拉拔力之量測,綜合本研 究之結果如下:

利用萬能材料試驗機對其做正向拉拔力之量測,可以得到可以觀察 到隨著甲基三甲氧基矽烷壓克力單體(6070)添加的量上升,相對應正向 拉拔力有提高的現象,然而添加甲基三甲氧基矽烷壓克力單體(6070)的 量過多,相對應正向拉拔力沒有繼續往上提升反而下降。
