High‐quality, few‐layer black‐phosphorus (BP) flakes are prepared in a common organic solvent with very short processing times using microwave‐assisted liquid‐phase exfoliation. A comprehensive range of analysis, combined with density‐functional theory calculations, confirms that the product prepared using the microwave technique is few‐layer BP with small‐ and large‐area flakes. The suspended exfoliated BP sheets show excellent stability, while samples dispersed onto silicon from the suspensions exhibit low oxidation levels after several days in ambient conditions. This straightforward synthesis method is facile, efficient, and extremely fast, and does not involve use of any surfactant or ultrasonication steps and will facilitate future development of phosphorene research.

微波辅助液相剥落技术快速高效地合成几层黑磷

使用微波辅助液相剥离技术，可以在很短的处理时间下，在普通有机溶剂中制备高质量，少层的黑磷（BP）薄片。广泛的分析范围与密度泛函理论计算相结合，证实了使用微波技术制备的产品是具有小面积和大面积薄片的多层BP。悬浮的剥离BP片材表现出出色的稳定性，而在室温下放置几天后，从悬浮液分散到硅片上的样品显示出较低的氧化水平。这种简单的合成方法简便，高效且非常快速，并且不涉及使用任何表面活性剂或超声处理步骤，并且将促进磷烯研究的未来发展。
