摘要：

The interparticle spacing of a heterostructure is a crucial factor affecting electron transfer (ET) process. Herein, binary nanoparticle superlattices (BNSLs) composed of CdSe/ZnS quantum dots (QDs) and Au nanoclusters (NCs) are prepared. Steady-state and time-resolved spectra illustrate that the ET accelerates as the pressure increases because pressure effectively adjusts the interparticle spacing. The results also demonstrate that the trap state of the CdSe/ZnS QDs affects the ET process of BNSLs.
