摘要: | 我們利用一鍋反應,合成出高品質的奈米晶體,並將其表面化學置換,接上有用的過渡金屬,當做單態氧的敏化劑,用在生物方面,可以得到高密度的氧氣及II-VI族奈米晶體的放光. We have prepared CdSe/ZnX (X= S, Se) quantum dots from the CdO precursor through a convenient, one-pot approach to maintain simplicity and green chemistry.39 Various characterization experiments provide unambiguous evidence for the core/shell nanoparticles formation. The feasibility of synthesizing tunable-size core/shell quantum dots may be considered an advantage, although the growing mechanism seems relatively complicated, as it may simultaneous incorporate the growth of core and the shell passivation. Nevertheless, the synthetic scheme described here optimized and finely controlled the defocusing stage, so that high-quality core/shell CdSe/ZnX quantum dots can be prepared in a one-pot synthesis. |
