Abstract

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.

优化ZnSe/ZnS量子点壳层厚度，增强三重态能量传递和光子上转换。

系统地研究了壳层厚度对ZnSe/ZnS-BCA混合体系中三重态能量传递效率的影响。ZnSe/ZnS的最佳壳层厚度有效地抑制了表面阱态，同时保持了足够的波函数重叠，从而促进了高效的TET，并表现出最高的上转换量子产率。
