non-radiative quenching

https://doi.org/10.1351/goldbook.08744
Deactivation of an electronically-excited state by interaction with the external environment through a non-radiative process.
Notes:
  1. Non-radiative quenching may lead to spectral shift or counting losses.
  2. The effects of quenching may be taken into account by a quenching correction.
