Sreekanth Mandati对Susanne Siebentritt的一篇论文进行了一般性的讨论：如果PL峰的半高宽（FWHM）更大，准费米能级分裂（qFls）是否准确（https：//doi. org/10.1039/d2fd00057a）？如果我们有肩峰怎么办？Susanne Siebentritt回答说：如果室温下PL峰的FWHM为100 meV或更大，则qFls被低估了20 mV或更多。但是，如果你可以测量外部辐射效率（ERE）或光致发光量子产额（PLQY），你仍然可以得到可靠的非辐射损失测量。
Sreekanth Mandati opened a general discussion of one of the papers by Susanne Siebentritt: If the full width at half maximum (FWHM) of the PL peak is larger, is the quasi Fermi level splitting (qFls) accurate (https://doi. org/10.1039/d2fd00057a)? What if we have shoulder peaks?Susanne Siebentritt replied: If the FWHM of the PL peak at room temperature is 100 meV or larger, the qFls is underestimated by 20 mV or more. But if you can measure external radiative efficiency (ERE) or photoluminescence quantum yield (PLQY), you still get a reliable measurement of the non-radiative loss.
