时间分辨 Pl 中weight fraction 什么意思 是怎么算出来 的
|
|
文献中经常遇到time-resolved PL dacay 中有 不同decay lifetime的 weight fraction，请问具体是代表什么 怎么算出来的： Time resolved photoluminescence (PL) behavior was charac- terized to probe the infl uence of the enhanced crystallization of perovskite thin fi lms on charge dissociation. Detailed infor- mation regarding the preparation, measurement, and fi tting methodology can be found in the experimental section. The PL lifetime of the samples was fi tted with a bi-exponential decay function containing a fast decay and a slow decay process. We consider the fast decay process to be the result of the quenching of free carriers in the perovskite domain through transport to PEDOT  SS or PC 61 BM, and the slow decay process to be the result of radiative decay. Figure 5 displays the PL decay and the related parameters are summarized in Table 2 . For the pris- tine thin-fi lm perovskite, the fast decay lifetime is 12.9 ± 0.8 ns and the slow decay lifetime is 104 ± 3 ns while their weight fractions are 81% and 19% respectively, |
