Through efficient Förster resonance energy transfer, the near-infrared emission (850 nm) of a guest (weak near-infrared emitter)âhost (strong deep-red emitter) system is greatly enhanced by excitation of the host molecule at 508 nm, in comparison with excitation of the guest molecule at 660 nm.
通过有效的福斯特共振能量转移,客体(弱近红外发射体)-主体(强深红发射体)系统的近红外发射(850 nm)通过在508 nm激发主体分子而得到极大增强,而相比之下,在660 nm激发客体分子则效果不佳。
