Difference in extent of the Fermi energy and decrease of band-gapenergy for three kinds of CNTs show that CNT with one end open is favorable for the preparation of field emission electrode.
In the copolymers of fluorene and DBT, the efficient energy transfer due to exciton trapping on narrow band-gap DBT sites has been observed.
在芴与dbt的共聚物中，观察到了由于激子在低带隙单体DBT位置的捕获而产生的有效的能量转移。
