The close circle measurements of laser-induced white emission of graphene foam were performed. The measurements demonstrated the hysteresis loop dependent on excitation power. A notable reduction of the hysteresis loop area was observed upon decreasing excitation time. The origin of hysteresis loop is discussed in terms of formation of a metastable sp³ nanodomain within the graphene foam.

石墨烯泡沫激光诱导白光发射的闭环测量


对石墨烯泡沫的激光诱导白光发射进行了闭环测量。测量结果表明磁滞回线依赖于激励功率。减少激励时间后观察到磁滞回线面积显着减小。通过在石墨烯泡沫内形成亚稳态 sp ³ 纳米域来讨论磁滞回线的起源。
