本實驗使用溶膠－凝膠旋鍍法(Sol-gel spin coating)製作BFMO薄膜，由薄膜的穿透率光譜圖經由Tauc formula計算，成功地證實使用錳摻雜的方式可以使BFO的能隙降低，最多可降低約0.17eV左右。這將有助於在光學應用上能隙過大的BFO可以更有效率地轉換能量。
實驗還分別探討了鍍製在白金基板上的低錳摻雜量BFMO與鍍製在LNO緩衝層上高錳摻雜量BFMO，在不同氣氛下熱處理的基本性質、照光前後的性質等討論。除了透過XRD證實鍍製出的薄膜為BFMO鈣鈦礦結構單一相，LNO緩衝層的使用將有效地在摻雜量上升時降低第二相的產生。而透過介電常數與漏電性質的量測與XPS能譜的分析，發現除了BFO中部分的Fe3+會還原成Fe2+，摻雜錳在BFO中取代鐵原子的位置，也會因為錳在結構中形成一部分的Mn2+，因此透過電荷補償機制在薄膜中形成許多氧空缺，造成介電常數在低頻時數值過大以及漏電上升等現象。
BFMO在照光前後的性質，除了BFO展現光伏特性以外，摻雜錳的薄膜皆沒有光伏效應產生，這可能是因為氧空缺等空間電荷使得因照光產生的電子電洞對在分離後擴散到晶域的兩端前就發生了複合(Recombination)，使光伏效應消失。另一方面，所有BFMO薄膜在照光後皆有閉路電流上升的現象，根據文獻報導，這種光電導性質(Photoconductivity)的來源，原因之一可能就是氧空缺，這也符合我們在先前實驗的量測結果以及推論。
