What is quenching Stern-Volmer plot?

Image result for stern volmer quenching constant meaning
A Stern-Volmer plot is an elegant method of determining quantitative information (for example, rate constant) about fluorescence quenching when the nature of that quenching is reasonably well known; however, on its own, a single Stern-Volmer plot is unreliable for identifying how unknown quenching is mediated.

What is called quenching?

Quenching involves the rapid cooling of a metal to adjust the mechanical properties of its original state. To perform the quenching process, a metal is heated to a temperature greater than that of normal conditions, typically somewhere above its recrystallization temperature but below its melting temperature.
