Paper Abstract

Measuring the photoluminescence quantum yield (PLQY) is a method often used within numerous fields of luminescent material science. Determining its absolute value relies on counting photons and hence, it is a very sensitive technique. Therefore, systematic errors that may occur during the measurement are discussed widely. However, the statistical uncertainty within those measurements remains mainly unconsidered. Here, we propose a new way of data analyses that exploits multiple measurements and a subsequent evaluation using the weighted mean. This leads in an efficient way to a very low statistical uncertainty. Additionally, time-dependent influences on the measurement can be identified that way.
