    • 　　在本論文研究中，我們是第一位在水相下成功利用Na2SeSO3作為硒的前驅物，在溶液中依序加入硝酸、硒代硫酸鈉、醋酸鉛而溴化十六烷基三甲基銨鹽當保護劑，藉由改變硝酸、Na2SeSO3與醋酸鉛之間的莫爾比例，調控反應速率，我們成功地在水相下合成138到431奈米的硒化鉛立方體，藉由粉末X光繞射鑑定、穿透式電子顯微鏡電子繞射鑑定與掃描式電子顯微鏡影像拍攝可以了解硒化鉛立方體的成分與表面特性。

    　　In this work, we are the first one to utilize Na2SeSO3 as the Se precursor. By mixing aqueous HNO3, Na2SeSO3, and Pb(OAc)2 solutions, and changing their molar ratios, we have succeeded in PbSe cubes with tunable edge lengths varying from 138 nm to 431 nm. Transmission electron microscopy (TEM), energy dispersive X-ray spectroscopy(EDX), scanning electron microscopy (SEM) and powder X-ray diffraction (PXRD) patterns have been employed to characterize surface composition of the PbSe nanocubes.
