Time-resolved photoluminescence spectroscopy (TRPL) is an extension to normal spectroscopy in which a short laser pulse is used for excitation, and a fast detector is used to determine the emission of a material as a function of time after excitation. This technique can be used to measure material quality (higher quality material tends to have a longer emission time), to help identify spectral emissions with specific emissive states or to study energy transfer from one component to another in mixed systems, like solar cells.
