以XC-72炭黑为原料，采用化学氧化法制备单层和多层石墨烯量子点（GQDs），研究了一种简便、低成本、高产率的制备方法。单层GQDs被证明是细胞成像的优秀探针，而多层GQDs在光电器件中有很大的应用潜力。
A facile, low cost and high yield method has been developed to prepare single- and multi-layer graphene quantum dots (GQDs) from XC-72 carbon black by chemical oxidation. The single-layer GQDs are demonstrated to be excellent probes for cellular imaging, while the multi-layer GQDs may offer great potential applications in optoelectronic devices.
