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.
