Quantum yield is a measure of the efficiency of a photophysical or photochemical process, defined as the number of events occurring per photon absorbed. It indicates how many of the absorbed photons lead to a desired outcome, such as luminescence or chemical reaction. This concept is crucial in understanding the performance of quantum dots, particularly in terms of their synthesis and the ways in which their electronic and optical properties are harnessed for applications in fields like optoelectronics and biomedical imaging.
