Quantum-confined graphene-like electronic states are directly observed in graphene oxide and photothermally reduced graphene oxide via transient spectroscopy. An unexpected novel hybrid state arising from amorphous carbon-like peripheral structure with high sp(3) /sp(2) carbon ratio in close vicinity of confined graphene-like states is found commonly existent in various carbon nanomaterials, including graphene oxide, graphene quantum dots, and carbon dots.
通过瞬态光谱，在氧化石墨烯和光热还原氧化石墨烯中直接观察到量子限制的类石墨烯电子态。在各种碳纳米材料中，包括氧化石墨烯、石墨烯量子点和碳点，普遍存在一种来自无定形碳类似的外围结构与受限的类石墨烯态紧密相邻的高 sp(3) /sp(2) 碳比的新型混合态，这是出乎意料的。
