Silicon quantum dots (Si QDs) attract increasing interest nowadays due to their excellent optical and electronic properties. However, only a few optoelectronic organic molecules were reported as ligands of colloidal Si QDs. In this report, N-vinylcarbazole - a material widely used in the optoelectronics industry - was used for the modification of Si QDs as ligands. This hybrid nanomaterial exhibits different spectroscopic properties from either free ligands or Si QDs alone. Possible mechanisms were discussed. This type of new functional Si QDs may find application potentials in bioimaging, photovoltaic, or optoelectronic devices.
硅量子点（Si QDs）由于其优异的光学和电子性能，如今引起了越来越多的关注。然而，仅有少数光电有机分子被报道为胶体硅量子点的配体。在本报告中，N-乙烯基咔唑 - 一种广泛应用于光电行业的材料 - 被用作硅量子点的配体进行修饰。这种杂化纳米材料表现出与游离配体或单独的硅量子点不同的光谱性质。讨论了可能的机制。这种新型功能化硅量子点可能在生物成像、光伏或光电设备中有应用潜力。
