1. 生醫影像

將量子點和磁性磁材料整合到奈米二氧化矽球體內部,同時於表面修飾cisplatin白金抗癌藥物,形成一個多功能的奈米複合物。同時經由研究發現此多功能的奈米複合物能夠在MCF-7癌細胞治療,細胞螢光影像以及磁振造影三種生醫應用都有優異的表現。同時,藉由雙性崁段聚合物將疏水性的量子點進行相轉移,使其均勻分散在水溶液中。並利用開環反應使其表面形成縮酸基,而此官能基可以讓量子點表面以供價鍵方式與T1顯影劑和葉酸配位基形成具有對於癌細胞具備專一辨識性的奈米複合體,使其同時應用於細胞螢光影像以及核磁共振造影。

 

 

 

2. 太陽能電池

染料敏化太陽能電池由於因其電池結構簡單、製程便宜,已經逐漸受到重視。而其光電轉換效率受到光敏化劑、二氧化鈦光電極、電解液和對電極等部分的影響。其中以光敏化劑部分最為重要,而近年來半導體量子點逐漸取代傳統染料當做光敏化劑。近期我們藉由多層結構概念,形成以CuInS2為基礎的量子點敏化太陽能電池。其原理在於利用適當能隙差距,搭配緩衝層和共敏化層,可讓其特性具備80%外部量子效率,同時提高光電轉換效率。另外結合外部預合成(ex situ synthesis)和原位性合成(in situ synthesis)方式建構出的CuInS2量子點敏化太陽能電池。其中特色在於外部預合成的量子點部分可以經由表面化學修飾,獲得適當表面配位劑以達到緊密吸附於光電極;而原位性合成方式則利用連續式離子吸付反應(successive ionic-layer adsorption an d reaction,SILAR)均勻地大幅增加量子點附載效率增加光吸收效率。近期,提出綠色全水相的量子點敏化太陽能能夠達到8%以上的光電轉換效率。
