Quantum yield : ウィキペディア英語版
Quantum yield
The quantum yield (Φ) of a radiation-induced process is the number of times a specific event occurs per photon absorbed by the system. The "event" is typically a kind of chemical reaction.
==Applications==
The quantum yield for the decomposition of a reactant molecule in a decomposition reaction is defined as:
:: \Phi = \frac
Quantum yield can also be defined for other events, such as fluorescence:〔Lakowicz, Joseph R. ''Principles of Fluorescence Spectroscopy'' (Kluwer Academic / Plenum Publishers 1999) p.10. ISBN 978-0-387-31278-1〕
:: \Phi = \frac
Here, quantum yield is the emission efficiency of a given fluorophore.
