光诱导配体置换
Photoinduced Ligand DisplacementA phenomenon where photoexcitation triggers charge transfer at the surface of colloidal semiconductor nanocrystals (NCs), causing organic ligands to desorb from the surface. This process offers on-demand, out-of-equilibrium control of the ligand shell, distinct from conventional thermodynamic ligand exchange. / 一种光激发导致半导体纳米晶体表面电荷转移，进而引起有机配体从表面脱附的现象。该过程提供了对配体壳层的按需、非平衡控制，区别于传统的热力学配体交换。
