    Abstract: 在這次的研究當中,使用有機敏化劑Rose Bengal做為敏化劑,合成三個蒽的衍生物MEPA(9-(2-mesitylethynyl)-10-phenylanthracene)、BMEPA (4,4’-bis[9-(2-mesitylethynyl)-10-phenylanthracene])、TPEPAN (9-(triphenyl)ethynyl-10-phenylanthracene)做為發光體,在四氫呋喃和甲醇混合溶液中研究上轉移現象。以568 nm激發Rose Bengal,在450 nm發現上轉移現象,為綠光轉藍光上轉移。在激發光與放出光之間的反斯托克斯位移(anti-stoke shift)的大小為0.57 eV (MEPA、BMEPA)與0.72 eV (TPEPAN )。然而,在此系統中,Rose Bengal也有部分的螢光放射,在這兩種波長的放射下,使我們可觀測到白光的產生。
