摘　　要：在施主/受主荧光系统中，荧光猝灭可用于研究光致电子的转移。当样品中各组分的吸收谱及相应荧光谱存在严重交迭时，荧光检测不可避免地会受到内滤效应及荧光材料吸收深度的影响，造成猝灭率虚高的赝象。本文就三聚噻吩/富勒烯混合液的光谱校正进行研究，以便于正确评估施主与受主材料间的光致电子转移。In donor/acceptor fluorescent system, Photoinduced electron transfer can be observed via photoluminescence quenching. When the absorption spectra and corresponding fluorescence spectra of various components in a sample overlap seriously, the fluorescence detection wil inevitably be affected by the inner filter effect and the absorption depth from the fluorescence material, these directly leads to an artifact quenching efficiency. This paper investigates the fluorescence correction of trithiophene/ful erene mixture, in order to evaluate the electron transfer from donor to acceptor materials correctly.
