强辐射激光已被发现可使纳米碳灰颗粒内部发生快速的结构变化,甚至可用来直接制备出洋葱状的巴基葱。研究了作用面更广的辐射场,即微波与碳灰纳米颗粒之间的相互作用。以金属基底作辅助,发现玻璃真空腔中的样品在微波照射下亦出现快速的内部结构变化,并呈现出洋葱状的多缺陷巴基葱。利用高分辨透射电镜和气体发光等手段研究了这一变化过程,发现C2分子仍为这一过程中的最小基本单元,这为该结构的变化机理提供了有效依据。
Strong radiation lasers have been found to cause rapid structural changes within the nano-carbon soot particles and can even be used to directly produce onion-like barbage. The radiation field with wider action surface is studied, that is, the interaction between microwave and carbon nano-particles. Aided by a metal substrate, it was found that the samples in the glass vacuum chamber also showed rapid internal structural changes under microwave irradiation and exhibited onion-like, multiple-defect Baki onions. Using high-resolution transmission electron microscopy and gas luminescence and other means to study the change process and found that C2 molecules are still the smallest basic unit in this process, which provides an effective basis for the structure of the mechanism of change.
