中文摘要 據我們所知，本報告提供了在低/高油胺含量（OLA）的情況下一鍋法合成Zn0.5Cd0.5Se合金量子點（QD）的可能化學反應的示意圖。在高油胺含量下，由解析穿透式顯微鏡之量測結果顯示隨油胺含量提升從4到10 mL之Zn0.5Cd0.5Se之平均尺寸有顯著的提升從4到9 nm。[Zn(OAc)2]油胺複合材料可由Zn(OAc)2和油胺所合成。由傅里葉變換紅外光譜儀和X射線繞射儀數據證實，ZnO是由[Zn（OAc）2]-油胺複合物的熱分解形成的。由結果指出ZnO在Zn0.5Cd0.5Se表面上生長，因而增加了粒徑。在低油胺含量下，使用穿透式顯微鏡估算Zn0.5Cd0.5Se合成量子點之平均尺寸，大約為8，6及4 nm分別隨著不同之油胺含量0，2及4 mL。我們發現Zn（OAc）2和油胺可以形成[Zn（OAc）2]-油胺複合物，而此可抑制Zn0.5Cd0.5Se合成量子點之成長，由於降低了Zn(oleic acid)2 及Se2−的反應，進而使顆粒尺寸下降。
英文摘要 To the best of our knowledge, this report presents, for the first time, the schematic of the possible chemical reaction for a one-pot synthesis of Zn0.5Cd0.5Se alloy quantum dots (QDs) in the presence of low/high oleylamine (OLA) contents. For high OLA contents, high-resolution transmission electron microscopy (HRTEM) results showed that the average size of Zn0.5Cd0.5Se increases significantly from 4 to 9 nm with an increasing OLA content from 4 to 10 mL. First, [Zn(OAc)2]–OLA complex can be formed by a reaction between Zn(OAc)2 and OLA. Then, Fourier transform infrared (FTIR) spectroscopy and X-ray diffraction (XRD) data confirmed that ZnO is formed by thermal decomposition of the [Zn(OAc)2]–OLA complex. The results indicated that ZnO grew on the Zn0.5Cd0.5Se surface, thus increasing the particle size. For low OLA contents, HRTEM images were used to estimate the average sizes of the Zn0.5Cd0.5Se alloy QDs, which were approximately 8, 6, and 4 nm with OLA loadings of 0, 2, and 4 mL, respectively. We found that Zn(OAc)2 and OLA could form a [Zn(OAc)2]–OLA complex, which inhibited the growth of the Zn0.5Cd0.5Se alloy QDs, due to the decreasing reaction between Zn(oleic acid)2 and Se2−, which led to a decrease in particle size.
