量子產率（quantum yield）
量子產率的定義是指「發光分子的數目」與「被激發分子的總數」的比率
In a chemical photodegradation process, when a molecule dissociates after absorbing a light quantum, the quantum yield is the number of destroyed molecules divided by the number of photons absorbed by the system. Since not all photons are absorbed productively, the typical quantum yield will be less than 1.
