Abstract
None:
The effect of shell thickness on triplet energy transfer (TET) efficiency was systematically investigated in ZnSe/ZnS-BCA hybrid systems. The optimal shell thickness of ZnSe/ZnS effectively suppresses surface trap states while preserving sufficient wavefunction overlap to facilitate efficient TET, and exhibits the highest upconversion quantum yield.
