TRPL can provide a wealth of information about nanomaterials, including: - Carrier Dynamics: By analyzing the decay times, researchers can understand the recombination mechanisms of charge carriers, such as excitons and free carriers. - Energy Transfer: TRPL can reveal the efficiency of energy transfer processes between different components in composite materials. - Defect States: The presence of defects in nanomaterials can introduce non-radiative recombination pathways, which can be detected through changes in the decay profiles. - Surface Effects: Surface states and passivation can significantly influence the photoluminescence properties of nanoparticles and quantum dots.
